One man is dead and another is recovering after he was stabbed in the neck, stomach and chest over the weekend.

A court document identifies the man who was killed as Toby J. Armenta. Armenta’s death marks the city’s first homicide of the year.

Two people are behind bars over the incident.

Antoinette C. Armijo, 39, of the 2400 block of Yucca Street has been charged with voluntary manslaughter and aggravated battery, both third-degree felonies and with Tampering with evidence, a fourth degree felony. Her boyfriend, Johnny Montoya, 36, of the 100 block of Commerce Street has been charged with a single count of tampering with evidence for allegedly disposing of the knife used in the stabbing.

Both remained behind bars at the San Miguel County Detention Center as of late Monday afternoon.

The stabbing occurred early Saturday morning.

Arrest warrant affidavits filed in the cases state that Las Vegas police were dispatched to San Miguel Senior Apartment Complex H on the 2700 block of Collins Drive at 2:39 a.m. in reference to a man who had been stabbed. The responding officer found Steve Treiber on the northwest side of the apartment. Treiber had been stabbed in the neck, stomach and chest.

He told police he had been stabbed by an unknown woman. Paramedics arrived and transported Treiber to Alta Vista Regional Hospital.

After securing Treiber’s apartment, officers canvassed the area between North Star and San Miguel Apartment complexes. While canvassing the area they found a lifeless man lying on the cround in an open area next to an irrigation pond.

“During the interview of the surviving victim, Mr. Treiber, he indicated that he was stabbed by a female during an altercation,” according to the arrest warrant affidavit.

Based on their investigation, police identified Antoinette Armijo as a suspect in the stabbings, and they obtained an arrest warrant for her.

At 8:17 p.m. on Saturday, roughly 17 hours after the first call to dispatch, a city police officer pulled Armijo and Montoya over on the 100 block of Commerce. Both were detained and  transported to the Las Vegas police department.

Police say Armijo admitted to stabbing both men, but she said she did it to protect herself and Montoya, her boyfriend.

According to the affidavit, Armijo admitted to taking the knife from the scene. The same court document states that Montoya admitted to breaking the knife and throwing it by an automotive business on Legion Drive.

“Mr. Montoya took Las Vegas Police officers to the location, and a blade of a knife was located between the businesses of Subway and Cocina de Rafael,” court documents state.
