A judge has committed Jon David Guerrero to a state psychiatric facility after he was found mentally incompetent to stand trial in four murders in Mission Bay, Ocean Beach, and elsewhere.
San Diego Superior Court Judge Margo Woods read the psychiatric report on Guerrero, 40, and committed him July 26 for treatment. Another judge had suspended criminal proceedings July 14 and sent it to Woods to hear the report.
This is the second time Guerrero has been sent to Patton State Hospital for treatment. He was first sent in Oct., 2016, and returned here in March after doctors and a judge determined he had regained his competency.
Guerrero’s attorney, Dan Tandon, said his client suffers from “severe mental illness.”
Guerrero has yet to even have a preliminary hearing and Deputy District Attorney Makenzie Harvey had planned on presenting four days of witnesses in the grisly slayings that occurred a year ago.
Railroad spikes were plunged into the bodies of three of the murder victims and other survivors. The identification of two victims was found in Guerrero’s apartment after he was arrested on July 15, 2016.
The first homicide victim was Angelo DeNardo, 53, who was attacked where he was sleeping under the Interstate 5 bridge near Mission Bay on July 3, 2016. His body was set on fire after he died.
Shawn Longley, 41, died in Ocean Beach where he was sleeping on July 4, 2016. Another man was attacked in the Midway District after a railroad spike was driven into his sinus cavity and he survived, but was left blind.
The third murder victim was Dionicio Vahidy, 23, who was found dead on July 6, 2016, downtown. A fourth murder victim was Molly Simons, 83, who was walking to a bus stop in North Park on July 13, 2016 when she suffered a skull fracture. Simons is the only female victim.
He previously has pleaded not guilty. He is also charged with special circumstance allegations that allege multiple victims were killed. He is also charged with assaulting many victims who also survived.
