The man accused of shooting and killing a Yarmouth police officer on Cape Cod Thursday afternoon had 114 prior offenses as an adult, a law enforcement source tells Boston 25 News.
Yarmouth police Officer Sean Gannon was serving a warrant to Thomas Latanowich at a home in the Marstons Mills village in Barnstable when he was shot in the head and was killed, according to police.
After the shooting, police said Latanowich barricaded himself inside the Blueberry Lane home for more than an hour before he was arrested.
Officials say the warrant was being served to Latanowich for a probation violation related to several firearms violations and was out on bail from Middlesex County at the time of the shooting.
Latanowich, 29, is originally from Somerville but had several addresses on Cape Cod. He was arrested when he was 17-year-old at a South Yarmouth motel room and was charged with possession of cocaine with the intent to distribute, according to the Cape Cod Times.
And that was just the beginning of his long criminal history, which includes violent assaults, heroin trafficking and gun possession.
It’s unclear what Latanowich was doing at the Marstons Mills home. According to public land records he is not the owner.
On Friday, the 29-year-old accused killer appeared in court on murder charges. He is being held without bail and is due back in court on June 26.
