The man suspected of fatally shooting his ex-girlfriend and her boyfriend execution-style in the parking lot of a Bronx motel last weekend has committed suicide in Florida. Police were searching for Joseph Kernizan, 42, who they say killed his ex, 38-year-old Tracy Bennett, and 50-year-old Wayne Hamilton, as they emerged from the Holiday Motel on the New England Thruway around 3:15 a.m. Saturday morning. Kernizan was tracked down to an apartment in Miami by the New York-New Jersey Fugitive Regional Task Force around 11 p.m. yesterday. “As people started coming out, we heard gunshots ringing out," said US Marshall Barry Golden, who added they sent a robot with a mounted camera in. “That robot discovered a body down with weapons inside."

Witnesses said Bennett, who had a restraining order against Kernizan, begged for her and Hamilton's lives as Kernizan shot them both Saturday morning. According to the News' sources, Kernizan was the father of Bennett's two younger children and was "obsessed" with her—he was arrested in August after allegedly violating a protection order at the Long Island home he and Bennett had shared. Much of his anger was directed toward the married Hamilton, whom friends said had been secretly dating Bennett for five years.

Friends say that Hamilton, a Milwaukee reggae musician known as Captain Barkey, may have baited Kernizan with a 2010 song called "Nah Lef Joe," which many thought was about the affair. Hamilton's longtime music partner David "Wickerman" Taylor told the News the two men had feuded in the past when Hamilton was in town for shows; Wickerman said Kernizan once crashed a car into a vehicle carrying Hamilton and Bennett. "Everyone knew this was a bad situation," one NY-based reggae DJ told them. "People knew that this was going to end badly."
