Audiotapes from a 911 call released Tuesday night by the Kansas City Police Department portray a chaotic scene inside the upscale Independence, Mo., home moments after NFL standout Jovan Belcher shot and killed his girlfriend and drove off to the team's practice facility.

Belcher, 25, already had left the home after firing multiple gunshots and killing Kasandra Perkins, 22, when his mother made the emergency call to police.

As Belcher, a former two-sport star from West Babylon, drove his black Bentley to the Kansas City Chiefs' training facility, about five miles away, where he would kill himself, his mother, Cheryl Shepherd, alternately pleaded for help with the emergency responder and attempted to comfort a dying Perkins, the tapes show.

Shepherd was in town to help Belcher and Perkins with their 3-month-old daughter, Zoey, as the couple tried to sort out their troubled relationship.

But before 8 a.m. Sunday, Shepherd was trying to comfort Perkins as she lay dying -- shot multiple times by the Chiefs linebacker.

Shepherd can be heard pleading with an emergency operator to send help. At times she consoles the bleeding Perkins, who she refers to as Kasi, called "Cassie" and "Casandra" in the 911 transcripts. Zoey can be heard screaming in the background.

"Stay with me. You did the right thing," the unidentified dispatcher is heard telling Shepherd.

"It's a house. Please get the ambulance here, please. Oh my God," Shepherd shouts into the phone. "Oh my God Cassie. She's shot!"

"Your son did this?" the dispatcher asks.

Another voice can be heard faintly in the background.

"He shot me," is all Perkins is heard saying.

Again Shepherd pleads for help. "Please send an ambulance for Cassie! Please hurry!," she says. "The baby's crying!"

Shepherd then seems to recognize that Perkins, who just hours before had been out with friends at a Trey Songz concert, is slipping away.

"She's still breathing but please hurry," Shepherd says. "I don't know how much time she's got."

"They were arguing," the dispatcher says. "She's been shot?"

Shepherd turns her attention to Perkins.

"Casandra stay with me! The ambulance is on its way. You hear me? You hear me? Casandra? Stay with me!"

"Is she awake?" the dispatcher asks.

"Barely," Shepherd says, her voice cracking. "She's moving when I talk to her. Please God. Please just get the ambulance here."

The dispatcher asks about Belcher: "Where's your son?"

"He left," Shepherd says.

The dispatcher returns to what led up to the shooting. "OK," the dispatcher asks. "They were arguing and he shot her?"

"Yes," Shepherd says. "There were arguing."

The dispatcher presses Shepherd for more information about her son. "OK, what's your son's name?" the dispatcher asks.

Shepherd is silent. Screaming is heard in the background.
