INDIANAPOLIS -- The boyfriend of a woman found strangled to death in her home was arrested Friday in an attack on another woman.

Robert Sarver, 32, voluntarily talked with police Friday about the death of his girlfriend, Deneisha Watford, 28, who was killed sometime Wednesday in her home at 1831 Bauer Road, said Sgt. Paul Thompson.

Police said Sarver is considered a person of interest in the Watford's death, but he was arrested in connection with an attack on a different woman two weeks ago.

Investigators said Sarver choked and beat Tiesha Williams during an argument.

He was preliminarily charged with strangulation, criminal confinement, domestic battery, battery and being a serious violent felon in possession of a firearm in that case.

"We would have had him come in eventually, so he just came in on his own to talk about it but, he has not given us any information in regard to the Watford investigation," Thompson said.

Sarver's mug shot was not released Friday because Thompson said identification by witnesses in Watford's death was still ongoing.

Neighbors told 6News that they saw Watford with a man outside her home shortly before her death.

Anyone with information about the case is asked to call police or Crime Stoppers at 317-262-TIPS.
