Anchorage police have arrested and charged a man after police say he turned himself in for the fatal stabbing of a Joint Base Elmendorf-Richardson soldier. The crime happened early Sunday morning in an East Anchorage trailer court, and police are calling it a case of domestic violence.

Alvin Rodriguez-Moya, 40, has been charged with first-degree murder, second-degree murder, first-degree attempted murder, first degree assault and first-degree burglary, according to a statement from the Anchorage Police Department. Rodriguez-Moya is accused of fatally stabbing a man — who was later identified as 33-year-old Spc. Paolo Grassi — Sunday and seriously injuring a woman in the incident.

According to friends, Rodriguez-Moya dated the 56-year-old woman for 14 years before they broke up in November. Rodriguez-Moya moved out of the trailer the couple shared and into another trailer just two doors down.

Just after 3:30 a.m. Sunday, APD responded to a trailer on the 3000 block of Penland Parkway for a reported stabbing. Police found Grassi deceased inside the home with multiple stab wounds. His next of kin has been notified, police say. The woman, also found with multiple stab wounds, was found inside the home and hospitalized with life-threatening injuries. As of Monday morning she was in stable condition, APD says.

Based on damage to the residence and footage from a security camera next door, APD believes Rodriguez-Moya broke into the home, court documents say. The female victim’s daughter reported to police that she woke up around 3:30 a.m. to the sound of her mother screaming. She found her mother in the hallway, screaming that Rodriguez-Moya stabbed her, and saw the two men arguing in the living area.

The daughter told police she “grabbed her mother and fled down the hallway into another bedroom.” Rodriguez-Moya then allegedly kicked the door down and told his ex-girlfriend he would not kill her because of her daughter. According to the daughter, he then said, “I just killed him, go see.”

Rodriguez-Moya was “holding the knife loosely in his hand,” allowing the female victim’s daughter to take it from him and throw it into another bedroom, according to court documents.

Shortly after the killing, it appears Moya updated his Facebook page, writing in Spanish, “I killed a man.” The 40-year-old suspect fled the area, but contacted police around 9 p.m. Sunday to turn himself in. A citizen had also called police about spotting Rodriguez-Moya walking around East Anchorage around the same time. He was remanded to the Anchorage jail and was arraigned in court Monday afternoon.
