9. Stalking can be the product of a
number of different states of mind
9
10. 10
As a Normal behavior
• Aspirations as initiating or re-establishing a relationship
As a Crime
• Victim’s perceptions of being harassed and made them
fearful
It is not the intentions and behaviours of the
perpetrator that create a stalking event but how
the actions are experienced and articulated by the
victim

27. Zona’s Stalker–Victim Types
• Zona, Sharma, and Lane identified distinct stalker–victim
types dividing stalkers into three categories:
1. simple obsessional,
2. love obsessional, and
3. erotomanic
27
28. 1 Simple obsessional cases
• by far the most common,
• a stalking perpetrator and victim have some prior
knowledge of each other, and very often some prior
relationship.
• This relationship may be in the context of a work
environment (employer–employee), medical setting
(physician–patient), or may be an intimate relationship.
• motivated to coerce the victim back into the previous
relationship or to exact revenge for a one-sided termination
of the bond.
• Because there are fewer barriers to engage in physical
contact between stalker and victim, these cases have the
highest potential to result in violence
28
29. 2 Love obsessional stalking
• The stalker and stalked person (victim) have no prior
relationship.
• These stalkers are the type that victimizes celebrities,
known as the prototypical “obsessed fan.”
• Stalkers who perpetrate this type of behaviour are more
likely to have a DSM axis I diagnosis of severe and
persistent mental illness such as schizophrenia,
schizoaffective, or bipolar disorders.
• Stalkers in this category will often focus on their victim after
seeing him or her in public forum via media outlets.
29
30. Robert Bardo shot and killed actress Rebecca
Schaeffer
CA v. BARDO (1991)
30
Robert John Bardo, an obsessed fan, after stalking for 3 years, had
charged with the fatal 1989 shooting of young actress Rebecca Schaeffer.
The defence claims Bardo's mental illness has to blame for his actions.
Bardo faced a trial by judge and serving life imprisonment without
parole. Rebecca Schaeffer's murder ultimately led to the first anti-
stalking law.
31. 3 Erotomanic stalking
• a stalker delusionally believes that the stalking victim is
also in love with them.
• The rarest within Zona’s classification system,
• its overlap with the DSM-V diagnosis of delusional disorder,
Erotomanic type.
• A unique characteristic of this group is that the majority of
stalkers are females, often young women, whose victims
are classically men of higher socioeconomic status.
31
33. Rejected stalkers (35%)
• Rejection of relationship - mostly ex partner
• Also occurring with separation from the mother
• From a broken friendship
• From disrupted work relationship
• Majority had Personality Dx
• Some had DD , MJ
– Mixture of desire for both reconciliation and revenge
– Sense of loss combined with frustration, anger,
jealousy, cruelty, sadness
– Most likely to assault their victim
33
34. Intimacy seekers (33%)
• Seek intimacy with the object of their unwanted attention,
• Whom they have identified as their true love
• Commonly isolated, socially inept, possibly psychotic
• Central purpose – TO ESTABLISH A RELATIONSHIP
• Partners indifference –to their approaches – enraged them
• DD – erotomanic type (27)
• Schizophrenia (5)
• Mania (2)
• Morbid infatuations (15)
• Personality Dx (7)
34
35. Incompetent suitors (15%)
• Acknowledged that the object of their attention did not
reciprocate their affection
• Hoped that their behaviour would lead to intimacy
• Intellectually limited and socially incompetent persons
whose knowledge of courting was rudimentary
• Men with sense of entitlement to a partner but no capacity
/ willingness to start by social interaction
• Not infatuated; only attracted
• Had often previously stalked others
• Regarded their victims as attractive potential partners
35
36. Incompetent stalker differ from
intimacy seeker
✓ Did not award them with unique qualities
✓ Attracted but not infatuated (love-sick)
✓ Made no claims that there feelings were reciprocated
(mutually shared)
36
37. Resentful stalkers (11%)
• Stalked to frighten and distress the victim
• Some pursued a vendetta against specific victim (8)
– Ex: Stalked a medical practitioner failed to diagnose
wife's CA
• Some choose victim randomly
– Persistently pursued a young woman
• When stalker experienced a humiliating professional
rejection and
• When he glimpsed in the street,
• She appeared attractive,
• Wealthy, and
• Happy
37
38. • The resentful stalker experiences feelings of injustice and
desires revenge against their victim rather than a
relationship.
• Their behavior reflects their perception that they have been
humiliated and treated unfairly.
• viewing themselves as the victim
• The harassment is sustained by the satisfaction the stalker
obtains from the sense of power and control
• This group frequently issues overt and covert threats but
rarely resorts to physical violence in general
38
39. Mark Chapman, the notorious John
Lennon stalker and murderer is a
classic case of a resentful stalker
39
He described himself as the world’s biggest rock fan and admired
Lennon and all his work, until he read a biography of the musician.
Angered that Lennon would “preach love and peace but yet have
millions [of dollars],”
Diagnosed with Schizophrenia by 5/6 psychiatrists
40. Predatory stalkers (4%)
• Took pleasure in the sense of power produced by stalking
• Elements of
– Getting to know their victim
– Rehearsing their intended attack in fantasy
– Usually for sexual and voyeuristic gratification
• Predominantly had paraphilias
• The stalking is covert so as not to alert the victim to the
impending attack, but some derive pleasure from making
the victim aware of being watched without revealing his or
her own (the stalker’s) identity
• More likely than other groups to have previous convictions
for sexual offenses
40
41. RECON typology
• RECON classification system for stalking behaviour that
separates stalkers into four groups based on two key
domains.
• (i) the nature of the previous relationship between stalker
and victim (relationship, RE) and
• (ii) the context in which this relationship was based (context,
CON) as predictive of distinct categories of stalkers, especially
as they related to predicting risk of violent behaviour.
• Under this classification scheme,
– intimate and acquaintance stalkers (type I) have had
previous relationships with their victims, while
– public figure and private stranger stalkers (type II) have
not had previous relationships with their victims
41
42. TYPE I - Intimate stalkers
• those whom have been involved in an intimate relationship
(marriage, dating, sexual, cohabitating) with their victim.
• this group was the largest, making up 50% of all stalkers.
• This group was by far the most dangerous, being the most
likely to be
– violent,
– to use or to threaten use of weapons,
– to exhibit suicidal ideation or behaviour, and to
– abuse alcohol or other illicit substances.
• The majority are men
• recidivist stalking behaviour is near-universal despite
protection orders, incarceration, or other deterrents
42
43. TYPE I - Acquaintance stalkers
• Are known to their victims but
• have not been involved in an intimate or sexual
relationship.
• Examples of such relationships include
– work and other professional relationships,
– nonintimate friendships, and
– clinician– patient interactions.
• Strong desire to initiate a relationship, with
• sporadic pursuit patterns that often last years.
• They are less prone to violence than intimate stalkers
43
44. Type II - Public figure stalkers
• “celebrity stalkers” are those who stalk public personalities
with whom they have no prior relationship.
• are more likely to be psychotic, female, and have male
victims.
• celebrity stalkers are unlikely to threaten their victims or
perpetrate violence.
• Political stalkers???
44
45. Type II - Private stranger stalkers
• those who stalk someone who is not a public figure with
whom they have no prior relationship.
• Mostly made up of men with serious and persistent mental
illnesses.
• Up to one-third becoming violent in some capacity against
either the stalking object (victim) or his or her property.
45
47. Contact made by stalker
• Telephone calls– 87%
• Surveillance of home– 84%
• Followed– 80%
• Drive by home– 77%
• Appearing at workplace– 54%
• Sent letters– 50%
• Made other types of contact– 49%
• Spread gossip– 48%
47
48. Predictors of Type and Duration of Stalking
• Wide range of harassment behaviours seen in – REJECTED & RESENTFUL
• Personality Dx - used Most type of stalking methods
48
Calling by telephone – in all types
REJECTED - most likely to telephone
PREDATORY – least likely to telephone
51. False Victimization (FV)
• Very rare (2%)
• Usually, females
• Turns out the victim is the perpetrator
• Attention seeking behavior
• FVS Red Flags
– Come forward elatedly
– Wants to share all the details
– Expresses little fright
– Seems to be enjoying the attention
– Encourages police/3rd parties to set up a “meeting” so they can talk to
stalker
– Many have history of self mutilation / Suicide attempts
– False claims often follow major life distresses or dramatic moments
51
53. Association With Threats and Violence
• 48% - threatened their victims proceeded to assault them
• 77% - assaulted victims has threatened earlier
53
Threats Property damage Assault
Previous convictions Previous convictions Previous convictions
Substance abuse Substance abuse Substance abuse
Typology (resentful &
rejected)
54. Association With Threats and Violence
• Nonpsychotic stalkers more likely to assault
than psychotic stalkers
• Both are equally likely to threaten their
victims
54
55. Impact on Stalking Victims
• Anxiety (83%)
• Sleep disturbances (74%)
• Overwhelming Powerlessness (75%)
• Flashbacks/Intrusive recollections (55%)

55
56. Stalking Assessment
• Stalking Risk Profile: Guidelines for the Assessment and
Management of Stalkers (SRP)
• Stalking Assessment and Management (SAM)
– Above 18 years
– 30 factors into 3 domains
• Nature of Stalking
• Perpetrator Risk,
• Victim Vulnerability
– rationale behind this is to understand the motivations and
seriousness of the stalking behaviour, as well as which type of
stalker the perpetrator may be
– Overall ratings based on professional judgement / actuarial
56
57. Response to Management Strategies
• INTIMACY SEEKERS - Assertive psychiatric mx – address social isolation
– Resistant to judicial sanctions
• REJECTED STALKERS – many persuaded to stop by fines or incarceration
– Child custody disputes / MJ requires intervention
• INCOMPETENT STALKERS – abandon with relative ease – social skills training
– Challenge is to prevent them from choosing others
• RESENTFUL STALKERS – difficult to engage in Rx
– Legal punishment inflame their sense of grievance
• PREDATORY STALKERS – criminal justice issue + Rx paraphilias
57
58. Stalking Management
• Find motivation for stalking
• Look for psychiatric dx in stalker
• Address substance misuse
• Explore factors sustaining the behaviour
• Confront self deceptions that justify the behaviour
• Improve interpersonal and social skills
• Address victims psychological status and teaching empathy for victim
• Treat individually; group therapies as they build supportive networks
• Draw attention to consequences of behaviour
• Provide face saving exit (preserve reputation/ dignity/ credibility)
58
60. The criminal laws and offences principally employed
to prosecute stalking-related conduct
• The use of these laws to punish stalking would require multiple
prosecutions of the offender
• misdemeanour offences for trespass or malicious communications – fine
(unlikely to dissuade most stalkers or afford the victim any protection)
• anti-harassment laws such as menacing require an immediate threat of
violence against the victim - not applicable to many stalking situations
where threats are rarely explicit but rather implicit in the course of continued
following or surveillance
• restraining or non-molestation orders - onus is on the victim - sufficient
evidence of an imminent threat against his or her physical safety - notorious
difficulty of enforcing them
In practice these orders do little to abate stalking and frequently
serve to intensify the anger and determination of the perpetrator,
and precipitate an escalation to violence (Mullen & Pathé, 1994)
60
61. Anti Stalking law (1990)
• Criminal justice intervention was all too often stalled until the stalker ‘did
something’ – gap in the law
• After Rebecca Schaeffer’s murder - public outcry and media pressure and
the murders of four women from Orange County, California world’s first anti-
stalking statute in California
• stimulated public demand for specific laws prohibiting stalking
• The California legislature passed the bill in September 1990, defining the
offence of stalking as,
“any person who wilfully, maliciously, and repeatedly follows or
harasses another person and who makes a credible threat with the
intent to place that person in reasonable fear of death or great bodily
harm…”
61
62. • “Harasses” was defined as:
“a knowing and wilful course of conduct directed at a
specific person which seriously alarms, annoys or harasses
the person, and which serves no legitimate purpose. The
course of conduct must be such as would cause a
reasonable person to suffer substantial emotional distress,
and must actually cause substantial emotional distress to
the person.
“Course of conduct” means a pattern of conduct composed
of a series of acts over a period of time, however short,
evidencing a continuity of purpose. Constitutionally
protected activity is not included within the meaning of
course of conduct.”
62
63. • Misdemeanour Stalking is punished by
– a term of up to one year in a county jail,
– a fine of up to $1,000 or
– both a fine and imprisonment
• But Stalking also is punishable as part of California's “Three Strikes” sentencing
regime. If you're convicted of Felony Stalking, the penalty, without additional
enhancement, may be
– up to three years in a state prison,
– a fine of up to $10,000, or
– both a fine and imprisonment
• Note that if you accrue three “strikes” on your record you will serve at least 25
years in a state prison.
63
64. SUMMARY
• Defining stalker types is the first step toward the larger goal of creating
effective treatment strategies
• risk management instruments for stalking assessment are in their infancy
• currently no prospective studies that have examined different treatment
options in managing the stalking situation
• Options include legal, psychotherapeutic, psychopharmacologic, and
physical barrier-based methods
• In certain cases, interventions such as therapy and psychotropic drugs are
essential
• However, other stalking situations are best managed through legal means
including protection orders and incarceration of offenders
• Ideally, law enforcement agencies and mental health professionals would
work in concert to prevent negative outcomes in stalking situations and
prevent stalking recidivism
