Police Find 20,000 Rounds of Ammo Inside UPS Worker’s Home After Mass Shooting Threat

On March 1, 32-year-old Thomas Andrews was reported to Sunnyvale police after he sent threatening text messages to his employer. He told his boss that he was going to commit a mass shooting at the UPS facility where he worked.

Dan Pistor, the Sunnyvale police captain, told Associated Press, “He alluded to a mass shooting in his text messages. I definitely think we avoided a tragedy.”

They discovered that Andrews was the registered owner of a rifle and four handguns.

Officers immediately started searching for Andrews that day. They spotted him shortly after 11 pm driving in his car. When they attempted to pull him over, he fled, which started a pursuit on Highway 101.

The police eventually caught Andrews thanks to help from the California Highway Patrol. Pistor said, “Initially he indicated he wanted to fight with the officers, but then he surrendered without injury.”

He was captured near Bailey Road, and the Sunnyvale Department of Public Safety issued a statement about what transpired.

Detectives who later searched his home discovered rifle ammunition including several high-capacity magazines, over 20,000 rounds of handgun ammunition, a shotgun, body armor, three handguns, and five tactical style rifles.

We do not yet know if Andrews has sought lawyer advice.
