(WBNG Binghamton) A New York State parole officer is accused of shooting and killing his estranged wife and her boyfriend in Greene County, then killing himself after a high speed chase in Cortland County.

Robert Mroczek, 46, led New York State Police and the Cortland County Sheriff's Department on a high speed chase, traveling faster than 150 mph at times, early Monday morning.

It ended around 1:30 a.m. when one of Mroczek's tires hit a stop stick between exit 9 (Marathon) and exit 10 (McGraw), causing the car to go into a ditch.

State police said Mroczek was pronounced dead at the scene from a self inflicted gunshot wound to the head.

On Sunday, State Police at Catskill responded to a report of gunshots being fired at 844 Pennsylvania Ave., Palenville, N.Y.

Daniel Brennan, age 51 of Schenectady, N.Y., was found dead from multiple gunshot wounds in the driveway of the home.

Inside the home, state police found Pammi Mroczek, 49, dead from gunshot wounds.

Police said Brennan was the boyfriend of Pammi Mroczek, who lived at the home. Pammi Mroczek is the estranged wife of Robert Mroczek.

According to state police, Mroczek shot the two before taking off in a black 1986 Monte Carlo.

He was first spotted by State Police in Broome County, driving on Interstate 81 in the Town of Chenango.

Troopers tried to pull the car over, which led to a police chase spanning more than 30 miles.

I-81 North between exits 9 and 10 was shut down for a few hours Monday Morning, according to New York State DOT. It has since reopened.
