BROOKLYN - A man was arrested Saturday after police say he confessed to killing his girlfriend and her two lovers inside a Brownsville apartment.

According to investigators, the suspect claims he caught his 51-year-old girlfriend in the middle of a threesome. Neighbors at 1518 Eastern Parkway say they heard screams and the woman's dog barking Thursday night.

Police say the suspect claims he disposed of the remains of the two men he killed in New Jersey. However, neighbors do not believe there were other people in the apartment at the time of the murder.
