NEW YORK (CBSNewYork) — A mother and her grown daughter are dead, and a man was in critical condition late Wednesday, in a suspected double murder and attempted suicide in a Bronx building.

Police were called around 2:20 p.m. to the eleventh floor of the Trio Apartments building at 1690 E. 174th St. at the corner of Croes Avenue, in the Soundview section of the Bronx. Once they got inside, police found a gruesome scene.

In the apartment, officers discovered the body of a 54-year-old woman who was pronounced dead at the scene, as well as a 29-year-old woman who was rushed to NYC Health + Hospitals/Jacobi where she was also pronounced dead, Boyce said.

The 54-year-old woman was later identified as Susan Trivino, the 29-year-old woman as Suchari Guzman. Relatives and police sources said Trivino was Guzman’s mother.

The NYPD Crime Scene Unit collected evidence inside the apartment until the evening. Outside, Trivino’s mother was overcome with grief.

“I have to go upstairs first to see my daughter,” she cried in Spanish.

A 52-year-old man was also rushed to Jacobi, where he was in critical condition and was not expected to Survive, Boyce said. He suffered a gunshot wound to his head that was believed to be self-inflicted.

A 1-year-old girl was also found in the apartment and was unharmed, but was taken to Jacobi as a precaution, Boyce said.

Police recovered a 9mm handgun at the scene, Boyce said.

“I’m so sorry. It’s very shocking,” said Keisha Burroughs, who lives in the building. “Three people – it’s very shocking.”

Police believe the incident was a double murder and attempted suicide and was domestic in nature, Boyce said.

“Right now, that’s preliminary. We’re sorting these things out,” Boyce said.

Relatives said the hospitalized man was Trivino’s on-and-off boyfriend.

“She had been with him for three years,” Trivino’s mother said in Spanish. “She would leave him, go back to him.”

Trivino’s son walked into the gruesome scene, one relative said.

“Her son, when he came into the apartment he saw his mother, him and the other sister on the floor,” he said.

Neighbors described Trivino as a kind woman.

“She was a loving mom,” said neighbor Damaris Medina. “She was always there for her kids, making sure they were OK.”

A person was taken into custody late Wednesday, but that person was brought in to provide a scenario for police as they sort out what happened and he was not believed to be a suspect, Boyce said.
