A person wanted by Baltimore police for questioning about the shooting death of 3-year-old McKenzie Elliott surrendered Thursday on a probation violation warrant, law enforcement sources said.

The person is considered a suspect, and police hope by taking him off the streets that witnesses may come forward with information that can help detectives close the case, the sources said. The warrant was issued this week for a probation violation in a previous, unrelated case, court records show.

The Baltimore Sun is not identifying the suspect because he has not been formally charged.

McKenzie was fatally wounded by a stray bullet as she sat on her porch in Waverly on Aug. 1. Her funeral was held Friday morning at Israel Baptist Church. Two other people were wounded in the shooting.

Police Commissioner Anthony W. Batts had announced that his department would make an arrest in the case by the end of this week.

"We've been seeking a person of interest this entire week," Batts said at a news conference Friday. "We've been one step behind a person of interest that we've been looking for. We've served several search warrants. … We haven't slowed down; we won't slow down."

The probation agent for the suspect said he failed to show up on time for required office visits on three recent occasions, according to court documents.

Rick Binetti, a spokesman for the Department of Public Safety and Correctional Services, said probation officials have been working with police on the investigation.

A lawyer who represented the person in the previous case said he had not heard from his former client this week.
