Boyfriend held pregnant girlfriend captive in savage stabbing

A brutal Bronx man, after repeatedly stabbing his pregnant girlfriend, held the bleeding woman captive in their apartment for 30 terrifying minutes, prosecutors said.

Oscar Alvarez, 30, knifed ex-military paratrooper Livia Abreu in the chest and side during an argument early Tuesday in their home on Walton Ave. near E. 165th St.

Abreu, who was listed in critical but stable condition, lost the baby as blood poured from her wounds inside their third-floor residence near Yankee Stadium.

“The defendant prevented the complainant from leaving for approximately 30 minutes while she bled profusely from her wounds,” prosecutor Gregory Desire said during Alvarez’s brief arraignment in Bronx Criminal Court Tuesday night.

Desire said Alvarez confessed to detectives after surrendering — and initially insisted that Abreu, 30, was accidentally stabbed seven times.

“I changed my clothes and left in the car,” prosecutors quoted Alvarez as saying.

Officials said he fled the apartment and stole his girlfriend’s 2004 Jeep Cherokee before turning himself in to police about 3 1/2 hours after the 12:30 a.m. stabbing.

Alvarez, clad in a dark navy polo shirt and jeans, was ordered held without bail on attempted murder and other charges.

He said only “Yes ma’am,” when asked by Judge Bahati Pitt if he understood that an order of protection barred him from any contact with Abreu.

The girlfriend was still recovering from her wounds Wednesday at Lincoln Hospital. Abreu, despite her life-threatening injuries, made her way to a neighbor’s second-floor apartment and called for help.

Defense attorney Joshua Hadas, in addition to asking unsuccessfully for bail, argued against allowing media coverage inside the courtroom.

“I don’t believe there is any public interest that will be met ... the public is not interested in a spectacle,” he sad in an argument rejected by the judge.

“I’m not going to get into the facts of what happened at this time because the facts are premature,” he said. “He has no criminal history at all. He is a working man. He has spent the last 10 years working at a local store, where he has risen to the level of manager.”

Hadas argued that Alvarez is not a flight risk because he has family in the Bronx. The suspect’s aunt, a home health aide, was in the courtroom.

“I’m not asking you to release my client but I do believe that in this case, bail is appropriate,” he said.

Abreu was 26 weeks pregnant with Alvarez’s baby daughter when the attack occurred. She served as a paratrooper with the 82nd Airborne during her time in the military.
