Mawugbe said he looked outside and saw a tall man in a brown polo shirt firing a pistol.

‘He jumped into the car and drove away. He drove fast,’ he added. He said the man fired about ten times, and got into a light green Toyota Camry or Ford Taurus.

Bennett’s neighbors told the Daily News they often heard her and Keizan screaming at each other and police were regularly called to their tidy two-story home.

“We always heard them fighting,” said Carolina Manzano.

While neighbors described Bennett, a mother of three, as a sweet woman who was seen leaving her house every moing in nurse scrubs, they said Keizan stayed out late and often retued in flashy cars.

Hamilton's friends who stopped by the crime scene Saturday afteoon said he was originally from Jamaica but was now living in Milwaukee, Wisconsin.

‘I saw him last night at Memories playing dominoes,’ said Oneil Taylor, referring to a Bronx nightclub.

Another friend, an shuttle driver, said he had picked up Hamilton Friday from the airport and brought him to the Fenton Avenue club.
