Jovan Belcher's mother frantic on 911 call as woman died

• Cheryl Shepherd called 911 as Kasandra Perkins, 22, was bleeding on the bathroom floor
• Couple's infant daughter, Zoey, is heard crying in the background
• Shepherd to Perkins: 'The ambulance is on the way. You hear me? You hear me? Kasandra! Stay with me'

KANSAS CITY, Mo. — The mother of Kansas City Chiefs linebacker Jovan Belcher pleaded with 911 dispatchers and her son's dying girlfriend after he shot Kasandra Perkins on Saturday morning.

Cheryl Shepherd called for emergency assistance as Perkins, 22, was bleeding on the bathroom floor of the couple's Crysler Avenue home. In 911 audio obtained by USA TODAY Sports, Shepherd is heard asking dispatchers to send an ambulance to the home.

"She's still breathing but barely," Shepherd says on the tape. "Please hurry."

As Shepherd tries to answer questions from dispatchers, she pleads with Perkins. Shepherd told the dispatchers that Perkins could hear her and responded when she spoke to Perkins.

The couple's infant daughter, Zoey, is heard crying in the background as her grandmother pleads for help.

"Kasandra, stay with me," a frantic and distraught Shepherd says on the tape. "The ambulance is on the way. You hear me? You hear me? Kasandra! Stay with me."

The audio also includes a request for medical attention at the Chiefs' training facility, where Belcher fatally shot himself after he shot Perkins.

"It's a self-inflicted shooting," says a dispatcher on the tape. "They said it's a done deal. They've got a player who shot himself."

Shepherd was in the home when an argument between Belcher and Perkins, his longtime girlfriend, escalated to a violent end just before 8 a.m. on Saturday.

Shepherd does not give any indication on the tape what the couple argued about.

On Tuesday, Kansas City police released more information about Belcher's whereabouts on Friday night. Officers responded to a 911 call at 2:50 a.m. CT about a suspicious car and occupant on the 700 block of East Armour Boulevard.

They found Belcher, 25, asleep in his Bentley. He was cooperative when they woke him and said he was waiting for his girlfriend in the building. Officers asked him to call her, and a woman came to the door of the six-story brick building to let him in.

KCPD did not inquire about her identity. Neighbors identified her to the New York Post as Brittni Glass, who told the newspaper that she was with Belcher that night.
