Police have arrested a suspect wanted in connection with the shooting of two Illinois police officers that left one of them dead, while a second suspect remains at large, authorities said.

Darius Sullivan, 25, was taken into custody Friday morning without incident after authorities conducted a search warrant on a home in North Manchester, Indiana, police said. Narcotics and multiple weapons were found inside the home, according to Indiana State Police Sgt. Glen Fifield.

Sullivan had warrants out of Illinois for his arrest on first-degree murder, attempted murder and aggravated battery with a firearm charges, Fifield said, in connection with Wednesday’s fatal shooting at a hotel in Kankakee County, Illinois.

Bradley Police Department Sgt. Marlene Rittmanic, 49, was killed after responding to a noise complaint at a Comfort Inn, authorities said. Her partner, Officer Tyler Bailey, 27, was wounded in the shooting and remains hospitalized in critical condition, Illinois State Police said in an update Thursday night.

Sullivan, of Bourbonnais, Illinois, will be transferred to the Kankakee County Sheriff’s Department, Fifield said. Police are still determining his connection to the North Manchester residence. It is unclear if he has an attorney.

An arrest warrant has also been issued for a second suspect in connection with the shooting, Xandria Harris, 26, of Bradley, Illinois, state police said. She was not present at the North Manchester home when Sullivan was taken into custody, according to Fifield.

“We are actively looking for her,” Fifield said.

The Kankakee County Sheriff’s Office was offering a $25,000 reward for information that led to the arrest of Sullivan. Fifield said the reward still stands for information leading to the arrest of Harris.
