QUEENS — Boxer Trevis Hall, who was being questioned in the brutal killing of his girlfriend, wrote about the risks of revenge and anger on his Facebook page days before the woman was beaten and stabbed to death in Jamaica Monday.
Margarita Rivera, 31, a mother of two young children, was beaten with a metal pipe in the head and stabbed multiple times in the chest in broad daylight down the street from her Jamaica home on Watson Place, near Polhemus Avenue, police said. She was later pronounced dead at Jamaica Hospital.
As of Wednesday afternoon, the boxer, 28, known as “Black Mamba,” who won the Golden Gloves championship in 2009, had not been charged.
Sources said that Hall, who was discovered unconscious in a Dumpster miles away from the scene, has so far refused to talk to investigators.
According to the sources, doctors at Jamaica Hospital, where Hall was taken Monday, discovered that the boxer suffers from a heart condition that was previously unknown. He is currently being treated for it, sources said.
On Nov. 25, Hall wrote on his Facebook page that “while seeking revenge, dig two graves one for yourself.”
“I've learn Holding on to anger is like grasping a hot coal with the intent of throwing it at someone else; I'm the one who gets burned. If I get down and quarrel everyday, I'm saying prayers to the devil... .”
But he also wrote that “getting angry doesn't solve anything.”
“Using my brain and taking a much smarter approach dealing with all of life challenges will put everything where I need it to be,” he wrote, adding hashtag “#mustbewise.”
The following day, he also wrote: “Never do anything when you are in a temper people, for you will do everything wrong people," attributing the quote to Baltasar Gracian, a 17th-century Spanish Jesuit and philosopher. "Alot of live will be lost and nothing will get done.”
Hours after the incident, Hall was found unconscious and intoxicated, but otherwise uninjured in a dumpster in Richmond Hill, about 3 miles away from the scene, sources said.
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 sponsors the tournament.
He was also a Golden Gloves semifinalist as a bantamweight in the open class in 2010 and 2011.
Sources said that Hall was recently staying with his family in Far Rockaway, after he and Rivera had broken up a few weeks ago.
In early June, the boxer got into a fight with Rivera's 19-year-old stepson, who lived with her, sources said.
According to the criminal complaint, Hall punched the man in the face with a 2-pound dumbbell, breaking his cheekbone.
Hall pleaded guilty to misdemeanor assault on Oct. 7, 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, according to the Queens District Attorney's office.
On Nov. 26, Rivera reported that Hall stole her cell phone. The boxer was not charged in that incident.
Hall's lawyer in the assault case could not immediately be reached for comment.
