TRENTON -- A 34-year-old Trenton man shot several times late Monday died a few hours later in a hospital, becoming the city's first homicide this year.

Tian Thompson fell mortally wounded in the doorway of Dee Dee's Lounge & Liquor Store at about 10 p.m. in the 500 block of Brunswick Avenue, the Mercer County Prosecutor's Office said.

He died of multiple gunshot wounds to the head at Capital Health Regional Medical Center, about five blocks north on Brunswick Avenue.

The prosecutor's office gave no further details of the crime, or any possible motives, only saying it was under investigation by the county's homicide task force and city police.

No arrests or charges have been announced in the case.

Four hours earlier Monday, a man was shot in the arm as he sat in his car about a block away on Martin Luther King Jr. Boulevard, at Vine Street. Police and prosecutor's did not say if they are exploring any possible connections.

Thompson was a drug dealer who was a semi-regular at the bar, officials familiar with the case said.

Records show he was sentenced to prison on 2011 for drug convictions stemming from arrests in Trenton in 2007 and 2009.

On social media, Thompson was being mourned with the street name Dread.

Trenton finished 2016 with 21 homicides, up from 17 the year before.
