The suspected gunman in the shooting of an off-duty Milwaukee police detective was arrested after an hourslong standoff ended peacefully Tuesday.

Two months after Detective Andrew Wilkiewicz was shot after a botched carjacking in the city's Third Ward, Chief Jeffrey Norman confirmed in a news conference at the scene that Keasean J. Ellis-Brown, 19, was taken into custody.

The department urged members of the public to stay away from the 2900 block of N. 9th St. at about 3 p.m. because of a "tactical situation," according to a news release.

"This could’ve really had some horrible outcomes, but cooler heads prevail and the right type of behavior and attitudes was put forth," Norman said.

Ellis-Brown has already been charged with five felonies in connection with the Third Ward shooting, including attempted first-degree intentional homicide.

He is one of three teens charged in the incident and was the only one not to be taken into custody in the hours afterward. He has been at large since then and the FBI offered a $10,000 reward for information leading to his arrest.

Norman said around 11:30 a.m. Tuesday police received credible information that Ellis-Brown was inside a house along the 2900 block of North 9th Street, in the North Division neighborhood of Milwaukee's north side.

After arriving at the building – a duplex – Norman said Ellis-Brown refused to come out, prompting the arrival of tactical enforcement and crisis negotiation units.

Ellis-Brown exited the home around 3:30 p.m. Norman credited officers with showing "great patience."

With investigators still filing in and out of the home as he spoke, Norman said it was not yet known how long Ellis-Brown had been there, if anyone was staying with him or why he had been inside that particular building. He was not sure if any weapons were found inside.

A woman who lived in another unit of the home, who asked not to be named, said she hadn't seen Ellis-Brown before.

Timonte L. Karroll-Robinson and Dionta'e L. Hayes also are charged in connection with the Third Ward incident.

On Jan. 13, Wilkiewicz was inside of the Shack Shake, at 220 E. Buffalo St., when a delivery driver arrived outside the establishment. When the driver briefly exited the vehicle to ask if one of her three children could use the restroom, a man jumped inside of it, only to leave just as quickly after realizing kids were inside the car, according to the criminal complaint.

The man, identified in the complaint as Ellis-Brown, dropped his phone in the process, which was picked up by the driver. The man then followed her back inside the restaurant and tried to forcefully take back his phone, the complaint said.

Wilkiewicz then stepped in and identified himself as police. During the struggle, Wilkiewicz was shot nonfatally.

Ellis-Brown fled in another car with two other teens who dropped him off at his home, the complaint said. Surveillance footage from inside showed him leaving the home shortly afterwards after changing clothes. He was accompanied with another person carrying bags with various items and shoes inside.

Ellis-Brown and another teen were out on bail in other felony cases at the time of the incident, according to court records.
