Several cans of gasoline, 12 firearms and around 22,000 rounds of various types of ammunition were found by law enforcement at the home of the shooter who shot dead nine of his colleagues at a streetcar construction site in San Jose, Calif., Local authorities said. Friday. Authorities said the suspect, Samuel Cassidy, 57, “was prepared to use his guns to kill as many people as possible.”
“It is clear that this was a planned event,” said one declaration from the Santa Clara County Sheriff’s Office read.
On Wednesday, the county sheriff’s office received several 911 calls regarding shots fired at the Santa Clara Valley Transportation Authority at around 6:34 a.m. local time. Employees of the facility were evacuated from the building, which serves as a transit control center.
The shooter fired 39 shots and appeared to target some of the victims, employees of the Santa Clara Valley Transportation Authority, which operates the rail yard, Sheriff Laurie Smith told The Associated Press on Thursday.
The deputies did not exchange shots with the suspect, who then carried two semi-automatic handguns and 11 magazines with him. Investigators believe he died of a self-inflicted gunshot wound, deputy Russell Davis, a spokesperson for the sheriff’s department, said.
At around the same time as the shooting, San Jose Police and Fire Departments responded to a fire in what was later determined to be Cassidy’s home. The sheriff said he appeared to have set a timer or a slow-burning device to set his house on fire. Authorities believe the suspect coordinated the destruction of his home.
A bomb sniffer dog first detected explosive material at the crime scene, forcing officials to send a bomb squad to investigate “every crevice” in the facility, Davis said. As a result of the marshalling yard investigation, no explosives were found, officials reported on Friday.
Cassidy has been described by her colleagues at VTA as “unhappy,” the sheriff’s office said. His ex-wife, Cecilia Nelms, told CBS News he finds it hard to get angry. “It was one of our biggest problems. He was very calm, keep things to himself,” Nelms said.
The case is still ongoing. The authorities are still in the process of determining a motive.
