Three people were charged Friday in connection with a fatal shooting in the parking lot of an East Side apartment building that Madison police say was "a drug deal that turned violent."

An arrest warrant was filed for Anthony A. Williams, 19, of Madison, who is charged with first-degree intentional homicide in the death of Michael J. Keith Jr., 24, of Chicago.

Elizabeth N. Glasbrenner, 21, of Madison is in Dane County Jail on a charge of felony murder in the shooting that occurred just after midnight at Camelot Apartments, 1782 Fordem Avenue.

Keith died Friday morning at UW Hospital of a gunshot wound to the brain, according to a criminal complaint.

Glasbrenner and Williams also are charged with attempted first-degree intentional homicide in the shooting of Deondrea I. Stevenson, 22, of Chicago, who had a bullet fragment enter his chin and lodge in his spine, the complaint states. Police have said Stevenson's injury is not life-threatening.

Zachary L. Mays, 18, of Madison also is in Dane County Jail on two counts of conspiracy to commit armed robbery.

According to a complaint filed in Dane County Circuit Court:

A witness told police that he, Keith and Stevenson arranged to meet Glasbrenner, known as "Africa," at Camelot Apartments. When they arrived in the parking lot, they met Glasbrenner and another woman, who walked away and made a phone call. Less than two minutes later, the witness said, two men came up behind Keith and Stevenson and shot at them multiple times. The two men who fired then ran off with Glasbrenner and the other woman, the witness said.

Glassbrenner told police she had planned to rob Keith, known as "Payroll," whom she knew carried a large amount of money, and she asked Williams to help her.

She said the plan was for someone to come up with a fake gun and rob Keith and his companions. As she was talking to one of them, she said she heard several shots and ran from the scene, and denied having any involvement in the shooting.

Glasbrenner said Mays was in her residence in Camelot Apartments during the planning of the robbery and left her apartment with Williams prior to the shooting. Mays returned to her apartment moments after Williams following the shooting, she said.

The complaint, which accuses Williams of causing Keith's death, does not identify a second shooter.

Williams was not in custody as of late Friday, and police were still working on piecing together what took place, said Lt. Mary Lou Ricksecker.

"We believe that this was a drug deal that turned violent," said police spokesman Joel DeSpain.

DeSpain said police were looking for the person or people responsible for the shooting Friday.

"A lot of detectives are out and about," he said. "We've got people working around the clock."

The homicide is the sixth in the city this year. There were two in 2010.
