The Valley Transportation Authority has released more personnel files on the employee who killed nine of his colleagues in the deadliest mass shooting in Bay Area history last month.

According to reporting by KPIX, the nearly 100 pages of documents offer some insight into Samuel Cassidy’s work behavior as well as his personal life, including many minor incidents that altogether paint a troubling picture.

For instance, in 2008 Cassidy was reprimanded in a "written counseling" letter for missing 11 days of work in a one-year period.

In 2005, while on temporary disability for knee surgery, Cassidy failed to report to his supervisors every two weeks. He was warned he could be terminated if he failed to check-in.

And in 2019, Cassidy refused to sign out his portable radio after multiple requests, which is required when using the equipment. Cassidy was charged with insubordination and sent home without pay for two days.

Cassidy also missed work on occasion, according to the files, such as last August when he explained an absence on a "father emergency."

The documents included a statement from a co-worker who told a colleague that Cassidy, "scares me. If someone was to go postal, it’d be him."

The documents revealed several other incidents in the last year or so.

But despite his behavior, Cassidy continued to go to work unabated.

Until May 26, when he left opened fire on his colleagues in his workplace before turning the gun on himself.
