Man Beaten to Death on NY Subway by 33-Time Offender

A 64-year-old man was beaten to death on a New York City subway on Tuesday by a sword-wielding monster with at least 33 prior arrests.

David Mazariegos, 25, beat a complete stranger to death on the subway in downtown Brooklyn because he didn’t like the way he looked at him.

According to reports, Mazariegos became angry after the unidentified victim held the subway doors open for him. The act of kindness set him off and he brutally beat the victim for more than 10 minutes.

Mazariegos repeatedly punched the victim in the face and stomped on his head more than a dozen times, according to The New York Post.

The attacker stole the victim’s wallet and took off on foot. He was later arrested in Times Square with a samurai sword.

Mazariegos did not have his sword drawn. It was attached to his backpack.

The victim was rushed to New York-Presbyterian Hospital Brooklyn Methodist where he was pronounced dead.

The New York Post reported:

A deranged crook with a mile-long rap sheet allegedly confessed to savagely beating a stranger to death outside a Brooklyn subway station – coldly telling cops he didn’t like the way the victim “looked at him,” sources revealed Wednesday.

David Mazariegos, 25, was expected to be charged with murder in the senseless Tuesday afternoon assault near the Jay Street-MetroTech Station, law-enforcement sources said.

The creep flashed a sinister, partially toothless grin Wednesday as he was carted outside a Manhattan courthouse, where he was first arraigned on charges from a past case and his dramatic arrest with a samurai sword in Times Square hours after the brutal slaying.

“Why’d you take my planet?” Mazariegos raved outside the courtroom when asked why he killed the man.

Sources said the sicko allegedly copped to attacking the 64-year-old victim in Downtown Brooklyn because the hapless man held a subway gate door open for him – an act of kindness that the hotheaded hoodlum told cops he disliked.
