A neighbor and a friend provided the state with surveillance material and last-seen testimony that the court admitted as evidence. Gail Garcia testified she has Arlo cameras at her home, that she saved and provided footage to SAPD, and that State Exhibit 34 (the video clip) and map images were her recordings; she said, "I gave it to them." Defense counsel objected to authentication and missing metadata, but the court overruled those objections after Garcia and other witnesses confirmed they produced what they had and could identify their properties on the maps.
Juan Abrego, who testified he was with the victim the night before the death, said Robert left Abrego's home at about 10:40 p.m. in a red Volkswagen/Wagon; Abrego said Robert left voluntarily and that he did not see who was driving. Landlord Daniel Loredo testified he manages 205 West Hermitage and that his Lorax system recorded footage; he produced a disc (State Exhibit 37) and identified map exhibits (38 39) as fair depictions of the neighborhood layout. The defense repeatedly pressed whether timestamps, metadata, or full vendor files were included; witnesses said they provided the footage they possessed and the court admitted the exhibits for the jury to weigh.
