After nearly four days of ongoing investigation, the Iowa City police and other agencies will continue their manhunt for a suspect in the slaying of 30-year-old Donelle Derell Lindsey.

Iowa City police Lt. Bill Campbell said the department will continue to gather more information and pursue potential leads on the whereabouts of 27-year-old Brandon Brown.

"As we gather information and potential leads in this [case], we have reached out to a number of other agencies," Campbell said Sunday afternoon. "That happens almost immediately."

Iowa City police obtained an arrest warrant for Brown, who has been charged with first-degree murder. Brown is described as a black male, 5-9, 170 pounds, with black hair and blue eyes. While his current address is unknown, Brown has previously lived in Calumet City, Ill., and Harvey, Ill.

As of Sunday evening, Brown had not been arrested, and his whereabouts were unknown. According to police, he is considered armed and dangerous, and he may have fled to avoid arrest.

The reported shooting occurred around 11:30 p.m. Thursday on the 2400 block of Pestel Place.

Officers found Lindsey unresponsive and suffering from gunshot wounds. He was transported to the University of Iowa Hospitals and Clinics, where he was pronounced dead.

The UI released a Hawk Alert at around 12:06 a.m. June 22 pertaining to the shooting, stating "the shooting occurred in the area of Melrose and Mormon Trek. Police are looking for armed subject. If you are in the area, remain indoors, don’t confront suspect. Call 911 only if you have info or an emergency."

Dylan Nelson-Sease was getting ready for bed at approximately 11:20 p.m. with the window open when he heard a "domestic disturbance" outside.

Nelson-Sease told The Daily Iowan on June 22 he was not alarmed but continued to listen once he heard one of the men say, "Back down, homey; back down, homey." Right after hearing the scuffle, he heard four-consecutive gunshots and said it sounded like it had come from one gun.

At around 1 a.m. June 22, the Iowa City police, University Heights police, North Liberty police, Coralville police, the State Patrol, and the Johnson County Sheriff’s Office were all on scene; approximately half a block of Pestel Place was taped off by police.

According to an Iowa City police release, Brown was identified in a photo lineup as the shooter through eyewitness accounts and acquaintances of the suspect.

Police will continue to search until Brown is apprehended.
