A black "Powerline by Daisy" BB gun and an empty black magazine were recovered from the lower banister of the staircase. The handgun was examined and processed for possible latent fingerprints.
DNA samples recovered from the trigger, trigger guard, grip, hammer and slide of the BB gun were analyzed and compared with a reference sample obtained from Marquez. The analysis concluded that the DNA profile obtained from the trigger was approximately 1 x 1033 times more likely if it originated from Marquez than if it originated from an unknown individual.
The sample from the grip, hammer and slide was assumed to derive from two contributors, and was determined to be 4 x 1031 times more likely if it originated from Marquez and one unknown individual than if it originated from two unknown individuals.

Medical Examinations
Marquez was pronounced dead at Huntington Memorial Hospital at 2:36 p.m. An autopsy performed by the Los Angeles County Department of Medical Examiner-Coroner determined that Marquez sustained two gunshot wound-related abrasions to her right lateral chest area, under her right arm. [1] Marquez also sustained two gunshot wounds. The first was a gunshot wound to the lower back, slightly right of the midline. The track of the projectile was forward, slightly
- ↑ The abrasions were caused by bullet fragments that presumably resulted from the disintegration of bullets striking the wall and/or wood railing of the staircase.
