Three minutes and seven seconds after the call began the trip ended in a fatal collision at St. Mary Road and U.S. 190, according to a tape of the conversation.
Williamson’s family said earlier this week that she took the baby herself after being unable to get emergency assistance.
According to the tape, Williamson, 26, called the 911 Center at 3:21 p.m. on Feb. 11:
“I need an ambulance. My baby is turning red and stopped breathing. I’m at 330 East Maple. Oh my god, Oh my god,” Williams says.
By the time Acadian Ambulance is connected to her 48 seconds later and asks where she is located, she says:
“I’m on the way. I’m on East Maple. Oh my god, oh my god.”
The ambulance dispatcher asks again where she is and what’s going on:
“I'm trying to drive to the hospital. Oh my god. I’m going fast. She’s in my lap.”
At 3:22:51, the ambulance dispatcher tells her “slow down and be careful”.
She responds, her panic audible:
“I can’t handle this. I’m going to pass out.”
At 3:23:27, the ambulance dispatcher again asks where she is, adding, “You need to pull over and stop.”
By now on Hwy. 190, she responds she is at Ella Street.
At 3:23;40, the ambulance dispatcher again tells her to pull over and stop.
Crying, she responds:
“I can’t stop. I’m sorry, I just can’t. I’ve got to make it to the hospital.”
At 3:24:07, gasping for breath, she says, “Oh my God” and there is the sound of the collision, followed by screams.
After that the emergency personnel are heard trying to determine what happened and where. Williamson had dropped the phone at the impact.
The driver of the other car, Verdie Schambaugh, 80, died at the scene. The infant, one-year-old Laila Williamson, is in guarded condition at Tulane Pediatric ICU. Eight-year-old Cade Williamson, who was also in his mother’s car, was treated for a leg fracture and released.
