More details emerged Monday about what sparked a fatal road rage shooting last week in Hammond.
Edgar Singleton, 61, a Cook County Sheriff's Department corrections officer, was charged with murder Saturday in the fatal shooting of Montrell Moss, 23, of the 3800 block of Butternut Street in East Chicago.
According to an arrest affidavit released Monday, Singleton shot Moss on Thursday night after Moss called Singleton a profanity and threw a cup of water at his minivan.
A woman who was traveling with Moss in a blue Buick LeSabre told police they were driving on Indianapolis Boulevard heading toward Chicago when Singleton's gold minivan began changing lanes and cut them off, the affidavit states.
Singleton was stopped at a red light waiting to turn into the Horseshoe Casino. Moss drove by, called Singleton a profanity and threw a Burger King cup of water at the man, according to the affidavit.
Police said Singleton fired a single shot from a 9 mm handgun, which struck Moss in the left side of the neck, before Singleton fled.
Moss was pronounced dead at 8:50 p.m. Thursday in the emergency room at Franciscan St. Margaret Health hospital in Hammond.
The woman was talking to police when she spotted the minivan allegedly involved in the shooting. Officers stopped Singleton and saw a Glock pistol on his right hip and a bullet casing on the passenger's seat, according to the affidavit.
Singleton told police he thought Moss was reaching for a handgun before he shot at Moss' car.
Singleton told police, "He was reaching for a gun, I shot," according to the affidavit.
Benjamin Breit, spokesman for the Cook County Sheriff's Department, said Singleton was been de-deputized as a result of his arrest and procedures are underway to terminate him.
Breit said Singleton was employed at the Cook County Jail at West 26th Street and California Avenue in Chicago.
Singleton is expected to appear in court for an initial hearing sometime this week.
