WAPPINGER, N.Y. – A Dutchess County corrections sergeant is accused of killing his ex-wife.

Timothy Alexander, 32, of Poughkeepsie, was charged Friday with second-degree murder in the death of 34-year-old Terrie DeGelormo, reported Phoughkeepsie Journal.

Until recently Alexander served as president of the Dutchess County Sheriff’s Employee Association.

“He is currently a sergeant in our corrections division,” said Undersheriff Kirk Imperati.

State police and emergency personnel responded to a home in Wappinger near All Angels Hill Road for a reported stabbing about 11 p.m. Thursday.

They rendered first aid, but it was unsuccessful. As a result of her injuries from an assault, DeGelormo was pronounced dead at the scene, police said.

“An unknown assailant fled the scene” before police arrived. Subsequent to the homicide, follow-up investigation led to the arrest of Alexander, DeGelormo’s ex-husband, police said.

“This was a heartbreaking tragedy, where a young mother lost her life due to domestic violence,” state police Capt. John Ryan said in a statement.

Alexander did not turn himself in, said Trooper Aaron Hicks, a state police spokesman. Nevertheless, the manner of arrest was undisclosed.

Consequently, he was arraigned in Wappinger Town Court and sent to the Dutchess County Jail. He is being held without bail.

However, because of the circumstances, he was transferred to the Putnam County Jail, Imperati said. He is due back in court Wednesday.

Alexander previously used the name DeGelormo, such as when speaking to the Poughkeepsie Journal in his role as then-president of the sheriff’s employee union.

He changed his name in January 2017, according to records on file at the Dutchess County Clerk’s Office.

Shawn Merritt, the union’s current president, declined comment.

Alexander and DeGelormo separated in 2016. Moreover, a judgment of divorce was issued in 2017, records show. Photos on his Facebook page show Alexander remarried in August 2017, according to the Journal.

Anyone with information regarding the incident is asked to call state police at 845-677-7300. All calls can be kept confidential.
