A Suffolk Superior Court jury on Monday convicted Omay Tavares of shooting George "Jeffrey" Thompson to death on Rosseter Street on Jan. 7, 2010, the Suffolk County District Attorney's office reports.

The conviction on the first-degree murder charge means a mandatory sentence of life without possibility of parole. Tavares was scheduled for formal sentencing Tuesday morning.

Tavares said he was on Greenbrier Street, nowhere near Thompson's 87 Rosseter St. home, when Thompson was shot repeatedly. Prosecutors, however, showed that "cell phone and tower records proved that Tavares made the calls from his own cell phone, with those calls hitting towers close to Thompson's house," the DA's office says. In addition, a "pristine" fingerprint matching Tavares's was found on a doorknob at Rosseter Street.
