A man accused of killing his girlfriend of four days on Valentine's Day was held without bond Saturday on charges of premeditated murder.



Carlos Cadavid, 23, of Hollywood reported the death, which happened at the Grand Motel at 430 S. Federal Highway, as a suicide to the Broward Sheriff’s Office, according to an agency release.



Cadavid admitted to detectives Friday afternoon that he killed his girlfriend, whom he had only known for four days, the BSO said. He faces charges of first-degree murder and possession of methamphetamine, authorities said.



The BSO identified the victim as Krizia Nunez, 22, of Aventura.

Neighbor Juan Gonzalez said he saw the couple at Cadavid's house on Forrest Street in Hollywood, near Sheridan Street and Florida’s Turnpike.



“I saw him the other day with his girlfriend, but it's like a new girlfriend, it's not the one he used to have before,” Gonzalez said.



Homicide detectives noticed that the physical evidence in room 108 of the Grand Motel did not add up to a suicide. After an autopsy was done the Broward County Medical Examiner's Office agreed and ruled the woman's death a homicide, the BSO said.

Cadavid was being held at the Broward County Main Jail without bond Friday night, online jail records showed. It wasn't immediately known whether he has an attorney.



Authorities ask anyone with information on the incident to call Det. Bryan Tutler at 954-321-4210 or Broward County Crime Stoppers at 954-493-TIPS.
