The ex-husband of a woman shot execution-style in Staten Island on Tuesday evening has been placed in custody by a sheriff’s department in South Carolina, officials said.

John Galtieri, 61, a former police sergeant, was being detained in the town of Walterboro until New York police detectives arrive this morning. He is wanted for questioning in the murder of Jeanne Kane, 58, whom he divorced in 2003.

Kane was waiting for her daughter in her Volkswagen Jetta in the Pleasant Plains commuter lot in Staten Island when an assailant drove up beside her and shot her in the head. She was taken to Staten Island University South Hospital, where she was pronounced dead. No possessions were taken from her car, police said.

Court records show that Mr. Galtieri was recently ordered to pay his ex-wife $400,000 in damages because she suffered from “battered wife syndrome,” the Staten Island Advance reported.

Detectives advised U.S. marshals and the South Carolina Law Enforcement Division to be on the lookout for Mr. Galtieri’s car on Tuesday night.

Deputies stationed on I–95 spotted the car about 10:30 a.m. yesterday. Five officers performed a “felony car stop,” surrounding his car and ordering him to pull over and lie face-down on the ground. The arrest was made without incident, a spokesman, Chief Deputy Ted Stanfield, said.

The Colleton County Sheriff’s Office transported Mr. Galtieri’s car, which was not searched, to a contained area so NYPD investigators could analyze it for evidence, Deputy Stanfield said.

Mr. Galtieri has not been charged with a crime, and a lawyer had yet to be appointed yesterday afternoon, officials said.
