EUCLID, Ohio - Family members and community groups on Monday demanded that the Euclid Police Department release more information about the police shooting that claimed the life of an unarmed man.

Luke O. Stewart's relatives also chastised the department for allowing Officer Matthew Rhodes, the patrolman involved in the March 13 shooting, to return to full duty just days after the incident. A Euclid police spokesman said Monday that Rhodes returned to full duty March 25, but he declined to offer additional comment.

"They tell us nothing. They just kill my brother and say nothing," Stewart's brother, Cleander Stewart, said during a news conference Monday at the Cleveland law firm Friedman and Gilbert. "It makes no sense."

Investigators from the Euclid Police Department and the Ohio Bureau of Criminal Investigation have released few details about the confrontation that led to Stewart's death. The shooting happened just before 7 a.m. while officers were investigating a report of a suspicious vehicle.

City of Euclid officials have declined to release a copy of the incident report while the investigation is ongoing. The city has released body camera footage and police dispatch audio from the incident, as well as a copy of Rhodes' personnel file.

Civil rights attorneys Terry Gilbert, Jacqueline Greene and Sarah Gelsomino are representing Stewart's family and requested that the police department release more information, including the department's use-of-force policy and any previous complaints against officers who used deadly force.

Family members echoed the attorneys' requests during the news conference.

"What hurts the most about this is not knowing what happened," Stewart's cousin, Gregory Smith, said. "We know Luke. He was like a little brother to me. I know my cousin, and he wasn't a violent person."

Community organizations including the Cleveland branch of the NAACP, Black Lives Matter, Puncture the Silence and the Black Man's Army also spoke in support of Stewart's family.

Cleveland NAACP president Mike Nelson said Rhodes should be placed on restricted duty -- and not be allowed to carry a gun -- while the investigation into the shooting is ongoing.

"There's no reason for us to be here today, except for the behavior of a rogue police officer," Nelson said.

Investigators did not find a weapon inside Stewart's car, Ohio Bureau of Criminal Investigation spokeswoman Jill Del Greco said last month. Investigators are still trying to determine whether the car itself was used as a weapon, she said.

One officer told a police dispatcher that the driver tried to run them over, according to a police radio recording released last month. The officer also said in the recording that another officer was inside Stewart's car before the shooting.
