QUEENS — Trevis Hall, a boxer who won the Golden Gloves championship in 2009, is being questioned in the brutal killing of his girlfriend, a mom of two who was beaten stabbed to death in Jamaica Monday, sources said.
Margarita Rivera, 31, who has two young children, was beaten with a metal pipe in the head and stabbed multiple times in the chest Monday in broad daylight down the street from her Jamaica home, police said.
In a bizarre twist, sources said that Hall, 28, was found unconscious and intoxicated, but otherwise uninjured in a dumpster 3 miles away from the scene hours after the incident.
As of Tuesday afternoon, he had not been charged.
Hall, who was born in Georgetown, Guyana, won the Golden Gloves championship at a bantamweight in the novice class in 2009, according to the Daily News, which puts on the tournament. He was also a Golden Gloves semifinalist as a bantamweight in the open class in 2010 and 2011.
Witnesses said Rivera was beaten so badly with a metal pipe that she was unrecognizable and that one of the stab wounds was so large that it looked like she had been shot.
Witnesses said they saw a person hit Rivera with a pipe on Watson Place, near Polhemus Avenue around 2:30 p.m. before repeatedly stabbing her in the head and chest and running away, sources said.
She was pronounced dead at Jamaica Hospital, police said. Both the pipe and the knife were found at the scene, sources said.
Sources said that Hall and Rivera had broken up a few weeks ago and Hall was staying with his family in Far Rockaway.
In early June Hall got into a fight with Rivera's 19-year-old stepson, sources said..
According to the criminal complaint, Hall threatened the man with a knife and then punched him in the face with a 2-pound dumbbell, breaking his cheekbone.
According to the Queens District Attorney's office, Hall, who was charged with felony assault and criminal possession of a weapon, was released without bail.
He pleaded guilty to misdemeanor assault on Oct. 7, 2014, and was given a conditional discharge - meaning that the case would be dismissed if he stayed out of trouble for a certain period of time.
The victim in that case was given an order of protection, the Queens DA's office said.
Sources said that Rivera and Hall had no history of domestic violence. But on Nov. 26, Rivera reported that Hall stole her cell phone. Hall was not charged in that incident.
Sources said that Hall was found unconsious and intoxicated in a dumpster near a loading dock on 127th Street, between 89th and 91st aves in Richmond Hill, less than 3 miles from where Rivera was stabbed.
Police received a 911 call about a body found around 5 p.m. As of Tuesday afternoon, Hall was in police custody at Jamaica Hospital, according to the sources.
Toi Troy, 50, who runs a day care four doors down from where Rivera was beaten, said she came out of her house right after the stabbing.
Rivera, Troy said, was lying on the ground. "She was still breathing but she was out," she said. "Her face was so bloody I didn't even recognize her, and she had a stab wound to her heart so big that I thought it was a gunshot wound."
Neighbors said Rivera, who has lived on the block for about a year, was always seen with her two young children.
Troy said Rivera's daughter was in first grade, and her son, Justin, was 3.
"She was a sweet young lady," Troy said. "She was very beautiful too."
The Golden Gloves did not immediately respond to an email request for comment. Hall's family and lawyer in the assault case could not immediately be reached for comment.
