A man in Scottsdale has been arrested for killing his girlfriend during a fight and then erasing the memory on her cell phone before calling 911, according to authorities.
Scottsdale Police said 53-year-old Geoffrey Vandermatt was jailed on suspicion of second-degree murder and tampering with physical evidence.
Vandermate was released on a $ 200,000 bond pending court appearance.
It was not clear on Wednesday if Vandermate had a lawyer who could speak on his behalf.
Police said officers responded to Vandermatt’s apartment after he was told that his girlfriend was not moving or breathing.
The woman, whose name has not been released, was declared dead at the scene.
Medics said the woman showed signs of decomposition and had bruises around her neck.
Police said Vandermit changed his story several times, saying that he and his girlfriend had been in a drink for two weeks and the two had quarreled over the course of several days before her death, and several times escalated into physical altercations.
Vandermatt later said she tripped, fell and carried her dead body onto a sofa, according to court documents.
The documents also show that before calling the police, Vandermate erased the memory on his girlfriend’s phone and put it back to factory settings.
