FAIRFIELD — The double-murder jury trial for a young Vacaville man who shot and killed two friends and wounded a third friend after they all ate psilocybin mushrooms is nearing the home stretch.
Richard R. Calkins was 18 on Nov. 16, 2010, when he killed Richard M. Perez, 20, and Cameron S. Silva, 21, before shooting Sarah J. Berkheimer in the face. She survived.
Calkins’ defense attorney has had two expert witnesses testify that Calkins was unaware of the bloodshed that played out in his William Street apartment where the four friends had been playing video games and watching television up until the shooting starting.
Judge Donna Stashyn said Wednesday she was still undecided about whether or not another young man from Vacaville would be allowed to testify as a defense witness.
The potential witness, Alexander Cervantes, lived a few miles from Calkins’ house and claims to have ingested mushrooms he got from the same drug dealer Calkins used. Two weeks after Calkins’ arrest, Cervantes, then 14, raped, sodomized and repeatedly stabbed a 13-year-old girl and then repeatedly stabbed her baby brother in December 2010.
He was prosecuted as an adult and is serving a 68-years-to-life prison sentence.
Calkins’ attorney has said the mushroom connection between the two heinous crimes further illustrate for jurors how Calkins could not have been responsible for or cognizant of his actions.
