Toddler decapitated, her sister dead too after suspected DUI crash involving mom and aunt: 'She just stepped on the baby and walked to the grass'

Two toddlers are dead and two women are still in the hospital in serious condition after a horrific crash in North Las Vegas, Nevada, last weekend.

According to reports, Kaleah Sharelle Manning, 23, was driving a 2004 Honda Odyssey van around North Las Vegas last Sunday evening. Manning's sister, Raenysa Clydette-Glenn Washington, 25, sat next to her in the passenger seat, and Washington's two little girls, Taylor Wilmer, 3, and Rose Wilmer, 2, were in the backseat.

At approximately 9:15 p.m., Manning reportedly veered from her lane, struck a curb, and hit a small tree and light pole before crashing into a large palm tree head-on. Little Rose was decapitated in the crash and died at the scene. Taylor was rushed to University Medical Center, but she ultimately succumbed to her injuries the following day. Both girls were contained in adult seatbelts and not child car seat restraints, as is required by law, reports say.

Police at the scene claimed that Manning showed visible signs of intoxication, including slurred words and bloodshot eyes. She also frequently repeated herself and had a "strong odor of an alcoholic beverage emitting from her mouth every time she opened it to speak," police reported. She allegedly admitted to consuming two shots of alcohol. Blood alcohol level reports on both women are still pending.

Witnesses described a horrific scene and at least one fairly apathetic suspect. One teenager reported that one of the women appeared "nonchalant" about the crash that killed the two little girls.

"When she was getting out of the car, she just stepped on the baby and walked to the grass," the teen claimed.

Another apparent witness, Isaac Garcia, shared a similar story, claiming that one of the suspects just "left the baby there." There are other reports of one of the women picking up one of the girls and then dropping her.

The two adult sisters remain in the hospital in serious condition. They have also been placed under arrest and booked into Clark County Detention Center in absentia while they continue to receive medical treatment. Manning has been charged with:

• three counts of DUI resulting in substantial bodily harm or death,
• two counts of child neglect and endangerment resulting in death,
• two counts of operating a vehicle without child safety restraints,
• one count of operating a vehicle with a suspended registration,
• one count of having no proof of insurance, and
• one count of failing to maintain a travel lane.

The girls' grief-stricken father, Tavon Wilmer, 22, said the crash "should never have happened."

"My girls were beautiful, smart girls," he added.

Officer Alexander Cuevas of NLVPD said that the crash should serve as a warning to the entire community.

"This is a call to action about DUI, speed, and proper child restraints," Cuevas said.
