Gilbert E. Rochester, 66, charged with the murders of his estranged wife, Mary C. Lane and Lane's mother, Louise M. Cavuto Carrow.

The Delaware State Police Homicide Unit has arrested a 66-year-old Clayton man in the killings of his estranged wife and mother-in-law that occurred east of Smyrna on Sunday.

Police said Gilbert E. Rochester was charged with the murders of his estranged wife, Mary C. Lane, 56, and Lane's mother, Louise M. Cavuto Carrow, 80.

Rochester and Lane were in the process of a divorce, and she had been living with her mother and her 87-year-old stepfather at a home in the 300 block Hawkey Branch Road, police said.

Troopers were called to the residence around 7:42 a.m. on Sunday for a report of a male stabbing a female outside the home.

Troopers responded and found a woman dead in the driveway. Another woman was found dead inside a detached garage on the property.

The suspect initially fled the scene but was taken into custody shortly thereafter.

The preliminary investigation and witness interviews revealed that Rochester parked his silver Chevrolet Caprice approximately one mile east of the residence in a field entrance off Hawkey Branch Road and then walked to the house where he waited outside.

Sometime between 7:20 a.m. and 7:30 a.m., Carrow exited her home and began walking to the detached garage to leave for church. Rochester assaulted Carrow, causing her death, police said.

Shortly after that, Lane exited the home and began walking to the garage when she was attacked by Rochester in the driveway and stabbed to death before he fled the on foot, police said.

Neighbors heard screams coming from the area of the home, went out to see what was happening, and witnessed the attack on Lane while calling 9-1-1.

Troopers and an officer from the Clayton Police Department located the two victims and soon found Rochester hiding in some nearby woods on the property.

Police said Rochester still had a knife and didn't respond to commands to drop it, and so the Clayton police officer used a departmentally-issued Taser to temporarily incapacitate Rochester.

Rochester was transported by emergency medical services to an area hospital where he received medical treatment from the use of the Taser.

He was then transported to Delaware State Police Troop 3 in Camden where he was charged with two counts of first-degree murder and two counts of possession of a deadly weapon during the commission of a felony. He was arraigned at Justice of the Peace Court 7 and is being held without bail at James T. Vaughn Correctional Center near Smyrna.

Carrow and Lane were removed from the scene by personnel from the Delaware Division of Forensic Science who will conduct autopsies.
