Juan Cerda, a 45-year-old Hispanic man, was shot and killed inside his van on May 7, 2006, in San Antonio, Texas. His death occurred during a crime spree that, about 20 minutes later, also claimed the life of Beeville police officer Gregory Stewart, who was gunned down while walking.

Authorities arrested three teenagers in connection with both killings: Vincent Jessamy, 18; Marcus Anthony Acevedo, 19; and Jeremy Miera, 18. All three were charged with capital murder. Jessamy faced an additional charge of being an escaped felon. Investigators say the trio had allegedly robbed a teenage girl earlier in the spree, and a witness later told police the suspects had spoken about the crimes — a statement that helped lead to their arrests.

The case hinged on evidence from the scenes and the witness testimony. Does anyone have information about Juan Cerda, his routine, or what happened that day that could add context to the investigation?
