Glendale - Pierre Gardner has been charged with shooting and killing his 19-year-old girlfriend Nya Hammond on Sept. 26 in the parking lot of Orthopaedic Hospital of Wisconsin, where she worked as a cleaner.

Gardner, 21, and Hammond lived together in Milwaukee and had a 3-year-old child together. Hammond moved in with family members three weeks prior to the murder, telling multiple people that Gardner abused her and threatened her. After several attempts to contact her at her new home, Gardner met her at her workplace around 5:30 a.m. Monday, Sept. 16, and shot her in the parking lot, according to a criminal complaint.

Security footage shows Gardner's vehicle in the Orthopaedic Hospital of Wisconsin parking lot during the murder. Gardner was seen exiting the vehicle and meeting Hammond in the parking lot. They both got inside his vehicle, and three minutes later, the car began to leave the parking lot. While the car was stopped at the entrance of the driveway, Hammond exited the vehicle and moved toward a security guard station. At the same time, Gardner is seen exiting the vehicle and shooting a gun, according to a criminal complaint.

According to the complaint, a security guard said Hammond ran away from Gardner's car and toward his security vehicle. She could not speak and had blood coming from her mouth, according to the complaint. When Glendale police arrived, Hammond's breathing was shallow and she was unable to tell the officer what occurred.

The Milwaukee County Medical Examiner's Office found the bullet entered Hammond's back, to the right of the spine, and exited on the right side of her chest. The medical examiner also found scarring on the left side of Hammond's chest, abdomen, hip and leg, which appeared to be consistent with Hammond's allegations that Gardner whipped her with an extension cord, according to a criminal complaint.

Hammond had spoken about Gardner's abusive behavior to her family members and her supervisor, who told police that Gardner had previously threatened to shoot Hammond.

Milwaukee police located Gardner's car four days after the murder in the 3400 block of North 9th Street in Milwaukee. The vehicle was running and several windows were broken.

Gardner's mother said that after she found out about the murder, she found Gardner sitting in a bathtub and did not answer her questions about the murder. According to the complaint, he looked at her in a way she had never seen before.

Gardner was charged in Milwaukee County Circuit Court on Friday, Sept. 30, with first-degree reckless homicide with use of a dangerous weapon. If convicted, he faces a maximum 65 years in prison.
