The trial of Guillermo Perez and Alejandra Munoz continued on Friday with the defense calling multiple witnesses, including Munoz's brother and the lead detective on the case. Prosecutors questioned the witnesses about Perez's past work for Munoz's brother and Munoz's claim that she was at the scene to buy drugs, not to kill anyone. The detective maintained that the evidence showed planning before the shooting, in which Perez allegedly shot and killed Martin while on rollerblades.

Why it matters

This case has drawn significant attention due to the unusual circumstances of the shooting, with the alleged gunman on rollerblades, as well as the potential motive of a large settlement payment that the victim had agreed to accept just days before his death. The trial is seen as an important test of the prosecution's evidence and the defense's arguments.

The details

Perez and Munoz are charged in the killing of 70-year-old Richard Martin, who was shot while sitting inside his car at a shopping center in Fresno in May 2022. The defense called several witnesses on Friday, including Munoz's brother, who testified that he does not speak with his sister often and does not know much about Perez. Prosecutors questioned the brother about Perez's past work for him. The lead detective in the case, Ryan Rockwell, also testified, standing by his conclusions that the evidence showed planning before the shooting. Rockwell said surveillance video from the scene is part of the evidence.

  • The shooting occurred on May 17, 2022.
