Update: Investigation continues in Friday's auto accident deaths

Lawton_UPDATE:  The sole survivor of the crash is in critical condition.  The baby's uncle is worried that the child may have brain damage from injuries sustained in the accident.

Fort Sill Federal Credit Union has opened an account to help with the family's expenses.  To donate to the account, go to any of the credit union branches and specify the FBO account for benefit of Brenda Waters-Walker.

The investigation continues Monday morning into a devastating car accident near Medicine Park.  It claimed the lives of five people Friday night.

And now the relatives of those lost are trying to come to grips with the tragedy.  Brenda Waters-Walker says it's worst thing that could ever happen to her.  Her daughter Shawtrea Waters, and grandson Kylen Smiling were two of the five people killed in the crash.

"Screamin, howlin, its a dream its a dream, then you just..you never imagine your child especially your only child you see her at Thanksgiving, and then you dont see her anymore," says Brenda.

Waters boyfriend Terrence Nash was also killed.  Their one-year-old son Xavien Nash was the only survivor.  He's expected to be okay.

Brenda Waters-Walker says the family, along with the other victims Leticia Washington-Brown who was driving and her niece Jabarious Birdine were returning to Lawton on Friday after visiting family.

From what I hear from the highway patrol I guess she was reaching down to get something out of the seat, rose up and then overcorrected hit the siderail, and then it flipped off the bridge.  Pure accident," says Brenda.

As we've reported, her grandson, Kylen, was a student at Woodland Hills Elementary.  Teachers at the school are preparing to help the other students cope with the loss of their classmate.
