FRAMINGHAM, Mass. — Police say a Massachusetts man fought four people, including a pregnant woman, as his dog, which was also pregnant, died in the back seat of a hot car.

The MetroWest Daily News reports that 29-year-old Alberto Carmenatty pleaded not guilty Thursday to multiple assault and other charges.

Police say the Chelsea man became aggravated Wednesday at Hopkinton State Park and fought with his girlfriend, her two daughters and another relative. One daughter is pregnant. Authorities say Carmenatty also fought officers who responded to the scene and punched a security guard when he was brought to the hospital.

Prosecutors say Carmenatty's dog was later found dead in the car.

Carmenatty's lawyer says her client is the victim, noting his black eye and other injuries. Carmenatty is due in court next month.
