Time Line 0130 – 0500 9/25/1993  Early Saturday morning, after the bar “Anchors and Spurs” closed, a large crowd of bar patrons went to 805 and Palm to build a bonfire and continue partying.  A group of about 30 - 50 people, mostly all USN, had gathered at one bonfire at 0130.  Ellisand Combs were seen at this bonfire between 0130 and 0500.  Theirbodies were discovered at 0745hrs.
  15. 15. SCENE PROCESSING: Items of evidence from the crime scene were processed for fingerprints, 13 prints were found. These prints did not match either of the victims. They were run through AFIS with no hits. These prints still remain to be identified. Beer bottles/soda cans found at the scene did not contain usable fingerprints. The casings found at the scene were all .22 caliber and fired from the same weapon.
  16. 16. On 9/29/93, 17-year old LeopoldoCHAVEZ, was stopped while drivingELLIS’ truck in Baja California.The State Judicial police determinedthe vehicle was stolen. Chaveztaken into custody.
  17. 17.  CHAVEZ was a documented Otay Mesa gang member and went by the moniker “Weasel.” CHAVEZ would not talk to SDPD and was charged with auto theft in Mexico, but extradited back to San Diego on an unrelated Juvenile Court warrant for escaping from Juvenile Hall. CHAVEZ was brought to SDPD on 10/7/93, but again exercised his right to silence.
  18. 18. TRUCK PROCESSING Several fingerprints from the truck matched to CHAVEZ. Items of evidence were collected included 1 bottle, 1 cup, clothing, a bandage, etc. Red Cup Clothes & Bandage Fingerprints Bottle Fingerprints in Door Jam
  19. 19. INVESTIGATION OF CHAVEZ Three witnesses identified CHAVEZ from a photo line-up as being in the area just prior to the victims being killed.
  20. 20. WHY THE CASE WENT COLD At the time a search warrant of CHAVEZ’ family’s residence in Tijuana was requested but was denied by Mexican Judicial Police. No physical evidence (including fingerprints) linked CHAVEZ to the scene and no other viable suspects could be identified. The Juvenile DDA and Superior Court DDA assigned to see if the case could be issued along with escape charges against CHAVEZ decided there was insufficient evidence to charge CHAVEZ at that time.
  21. 21. SUBSEQUENT INVESTIGATION Case reviewed in 2000 by SDPD and inactivated in 2001. In 2002 the case was reviewed by NCIS. Their case was also inactivated. In 2009 a review of the case at the SDPD by NCIS Special Agent Kim Tedesco lead to a request to the SDPD Laboratory for DNA examination of various items of evidence from the crime scene.
