U.S. customs officials previously arrested the man who killed nine people in San Jose, Calif. On Wednesday and found he professed a hatred of his workplace where the shooting took place, according to a Department of Justice memo. internal security.
The shooter, Samuel James Cassidy, had “books on terrorism and fear and manifestos … as well as a black memo filled with many notes on how he hates the ATV”, when customs and border protection l ‘quit in 2016 after a trip to the Philippines, the note said.
The VTA is the Santa Clara Valley Transportation Authority, where he worked for at least nine years, according to public employment records.
“When asked if he was having problems with anyone at work, he said ‘no’,” according to the memo, a copy of which was viewed by The Wall Street Journal.
The shooting began at a union meeting at an VTA light rail station in downtown San Jose and all of the victims worked for the transportation authority. Eight people were found dead and a ninth died overnight in an area hospital. Cassidy died in an apparent suicide during the incident, law enforcement said.
The note was distributed within DHS shortly after Wednesday morning’s shooting. He does not say how long Cassidy has been detained by border officials.
The Journal could not immediately determine whether the findings of border officials had been communicated to the VTA or local law enforcement before the shooting.
A spokeswoman for the VTA addressed questions to the Santa Clara Sheriff’s Department. Spokesmen for the Santa Clara Sheriff’s Department, San Jose Police Department and U.S. Customs and Border Protection did not immediately respond to requests for comment.
A spokeswoman for the Department of Homeland Security, which oversees customs and border protection, declined to comment, citing the ongoing investigation into the shooting. She said the ministry began an internal review in February that includes “efforts to ensure law enforcement personnel have the tools and training to identify behavioral indicators associated with targeted violence. and policies to improve information sharing with our partners.
Santa Clara County Sheriff Laurie Smith told reporters Thursday morning that investigators had found no evidence indicating a possible motive.
Cassidy’s ex-girlfriend said she sexually assaulted her, according to documents she filed in 2009 with Santa Clara County Superior Court. She said Cassidy had bipolar disorder and “major mood swings” which were exacerbated when he consumed large amounts of alcohol.
She filed the statement in court in response to a domestic violence restraining order Cassidy had filed against her. She denied Cassidy’s accusations.
Robert G. Cummings, an attorney who represented Cassidy’s ex-girlfriend in the case, said he spoke to his former client and that she was shocked and saddened by Cassidy’s actions.
His ex-wife Cecilia Nelms told The Associated Press that he talked about killing people at work more than ten years ago. She said he would come back from work angry over assignments he considered unfair. The couple divorced in 2005 and Ms Nelms said they had not been in touch for 13 years.
Officers arrested and questioned Cassidy on August 8, 2016, after returning from a trip to the Philippines and inspecting her luggage and electronic media, the memo reads. The memo does not say why he was arrested. He notes that Cassidy had a “minor criminal history” and cites a 1983 incident in which he was arrested in San Jose and charged with “the offense of obstructing / resisting a peace officer”.
Sheriff Smith said Thursday Cassidy was armed with two semi-automatic handguns and 11 magazines at the time of the shooting. Bomb-sniffer dogs subsequently found explosive materials, but not devices, in a locker believed to be hers, she said.
On Wednesday morning, a fire broke out in a San Jose home that belonged to Cassidy, according to public records. Sheriff Smith told the Today Show he appeared to have detonated an explosive device in his home to coincide with the time of the shooting.
Local law enforcement officials found hundreds of cartridges inside the house, according to the DHS memo.
