California man charged with calling Somerville, Cambridge companies and threatening to head over with an AK-47 and kill everybody

A San Francisco man was arrested yesterday on charges he sent several voice-mail messages to two companies, one in Somerville, one in Cambridge, that he was furious at them and was planning to head over with an AK-47 and a handgun with a silencer and mow down everybody he can.

After receiving one of the calls, the Somerville company evacuated its offices, according to an affidavit by an FBI agent on the case, which does not name either company.

Daniel Nguyen, 34, who has been charged with making similar calls to San Francisco concerns in the past, will now be flown to Boston to face a federal charge of transmitting threats in interstate commerce.

According to the affidavit, Nguyen called the Somerville company four times in January and February, starting with a voice-mail message at 2:55 a.m. on Jan. 12:

Hey, you fucking assholes are dead…you hear me. You fucking cheated me, you screwed me out of money over here. I've got an AK-…I have an AK-47, you know, with a drum magazine and I've got a Glock with two silencers. I'm going to walk into [Company 1]…watch me, watch, I'm going to walk into [Company 1], I'm going to shoot up the whole fucking place with an AK-47. I'm going to shoot up the whole fucking [Company 1] office with an AK-47. And I've got a fucking Glock. I'm gonna shoot up the whole [Company 1] office with a Glock. You're all going to be fucking dead. It's going to be a fucking bloodbath. You hear me? I've got a fucking AK-47. I'm gonna shoot up the whole [Company 1] office. And you're all going to be fucking dead.

He then made two similar calls during business hours on Jan. 13, the affidavit continues. The agent then adds that in an interview, an employee at the company told him:

The employee expressed fear and concern for their life, as well as the lives of the other Company 1 employees. As a result of these voicemails, the building was evacuated and security was increased on company grounds.

Nguyen allegedly made one more threatening call to the company on Jan. 15. Meanwhile, at 2:49 a.m. on Jan. 12, he left a similar message on the voice mail of a Cambridge company, one in which he claimed to be an investor angry at how he had been screwed out of money.

Both companies used a Microsoft product for their phone systems, the affidavit continues. Microsoft then gave investigators IP addresses linked to the voice messages, which in turn led them to a T-Mobile number used by Nguyen. T-Mobile then provided call histories showing that Nguyen's phone was used to leave the five threatening messages to Somerville and Cambridge, the affidavit states.

According to records held by the SFPD, NGUYEN has previously made other violent threats via telephone call. On March 8, 2018, the SFPD received a report that NGUYEN called a company 8 and "stated several times that he wanted to go to the [company] and kill all of the 'Filipinos and wetbacks’ with an AK47."

On March 11, 2018, NGUYEN was arrested and charged by the SFPD for Terrorist Threats. According to SFPD reports, on or about March 10, 2018, NGUYEN called another business and stated: "I'm going to go to [the business] with my AK, stand in the middle of the store and tell everyone how I feel about Filipinos then spray the place."

On Sept. 4, armed with a search warrant, the FBI raided Nguyen's home and found the phone allegedly used for the threatening Massachusetts messages - and which allegedly had e-mail addresses that were used to send threatening messages to a high school in Nevada and a security company in California.

Based on the affidavit, a magistrate judge in US District Court in Boston issued an arrest warrant last week.

Innocent, etc.
