[Update below]

A man murdered his ex-girlfriend in the parking lot of South Ozone Park's Resorts World Casino when he saw her in a car with another man, then died hours later following a shootout with police in East New York, according to police. The Daily News reports:

The violence began about 2:20 a.m., when the 51-year-old man got into an argument with his ex [...] after seeing her kiss her new boyfriend in a parked car in the casino lot, sources said.

The suspect, who works for a charter bus company affilIated with the casino, got out of his car and opened fire on the woman and her new beau, sources said. The new boyfriend, a supervisor with the bus company, managed to escape unharmed and flee to his car while the suspect repeatedly fired at his ex-girlfriend’s car.

The woman, 55-year-old Patricia Mohammed, was pronounced dead at Jamaica Hospital and the man who killed her fled the scene in his Dodge Charger, according to police. Plainclothes officers then tracked the suspect, by pinging his cellphone, to Stanley and Pennsylvania Avenues in East New York around 6 am., according to the News.

The man shot at the three cops from his car as they drove up on him, and all of them returned fire, according to the NYPD. Cops said they recovered a .380-caliber handgun at the scene. Paramedics took the suspect to Brookdale Hospital, where he was pronounced dead. The Police Department is withholding his identity until his family has been notified.

Resorts World was the scene of a massive brawl in April during the opening of a Fat Tuesday daiquiri bar. In the aftermath, one man let off shots in the parking lot, but didn't hit anyone. Video posted later in the month showed another melee breaking out amid the slot machines, and an officer apparently using a chokehold to subdue a man. The so-called "racino" is attached to the Aqueduct Racetrack and does not include table games. It opened in 2011.

The murder and police killing this morning capped a violent weekend in the area. On Monday night, a 22-year-old man was shot and killed and a second was injured on New Lots Avenue at Elton Street in East New York. On Sunday afternoon, 54-year-old Russell Holdip was found dead, stabbed multiple times in the head, in his apartment on Grant Avenue in Cypress Hills.

Update 3:05 pm:

The late suspect has been identified as Dalton Branch, a two-time inmate who taunted Mohammed's relatives through calls and text-messages after her murder, declaring himself the "Grim Reaper," and telling his own family he wouldn't be taken alive, according to additional reporting by the Daily News:

A weeping Rosemarie Guilford, 75, told the Daily News that Branch called her home at 2:52 a.m. — about 30 minutes after he shot Mohamed as the woman cowered inside a parked car.

“He told me that I should prepare myself to bury my niece,” recalled the shaken Guilford about the terrifying calls. “And then he called back at 3 a.m.

“He told me, ‘I gave it to her good. She’s dead, so prepare yourself. And I could come and burn your house down.’ I couldn’t say anything. What was I going to say? ... He was a very brutal type of guy.”

[...] [Mohammed's] new boyfriend, after escaping with his life, received a mocking text from the killer.

“How you like that p---- now?” asked Branch.
