DERANGED STALKER SLAYS 2 EX-LOVERS

A crazed man stabbed his girlfriend to death yesterday in Queens, raced to Brooklyn and killed an ex-lover in front of their daughter – and finally went home to confess to a 911 operator, police said.

“I just killed two women, and I want to kill myself!” Lionel Michael King, 41, screamed to another friend during his bloody early-morning spree, cops said.

King, of Brooklyn, was recovering last night from what appeared to be severe self-inflicted knife wounds to his hands. Police said he may also have swallowed some liquid in an effort to take his life.

Investigators gave this account: Sometime between 5 a.m. and 7 a.m. King visited Dionne DeSouza, 29, at her home at 250-11 139th Ave., in Rosedale.

An argument erupted and King stabbed the mother of two in the neck and chest.

Police said DeSouza, a bank employee, was King’s most recent girlfriend, and neighbors said he visited daily – to harass her.

“He was stalking her. He was obsessed with her. He kept telling her he was bad news, but she didn’t listen,” Triana Powell said.

As DeSouza lay dying, King went to 778 Nostrand Ave., in Crown Heights, where he confronted Patsy Niles, the mother of their 5-year-old daughter, on the street outside Niles’ walkup.

Authorities said King repeatedly stabbed Niles in front of the girl, then fled the scene while she staggered upstairs.

Niles knocked on the bedroom door of another of her three children, a 14-year-old daughter, exclaimed, “Mickey chopped me!” and collapsed.

Niles sister, Denise, said her family wasn’t surprised by the attack because King had often beaten his ex-girlfriend and threatened to kill her.

Police said King, dripping blood, then went to Cleveland Street, where he banged on the apartment door of another woman friend and told her what he had done. The woman refused to let him in and called police.

King then went home to 529 E. 22nd Street in Brooklyn, where he called 911 and confessed. Police arrested him at about 10:20 a.m. and he made a more detailed confession last night.

He was charged with the two murders and criminal possession of a weapon, the knife, which he said belonged to DeSouza. He claimed she pulled it on him during their argument and he hid it in his car.

Police said King had been charged a year-and-a-half ago with assaulting Niles, but the case was dropped when she refused to cooperate.
