WICHITA, Kan. (KAKE) - A newly released court document provides details of a crash that killed a 4-year-old Kansas girl and landed her mother in jail. 

Britne Costello, 33, is charged with involuntary manslaughter while driving under the influence and aggravated battery in connection to the crash on February 19, 2023. She remains jailed on $250,000 bond.

At around 5:30 p.m. that day, a deputy was heading east on MacArthur from 215th Street West, south of Goddard, when he saw a westbound white Ford Explorer airborne over the northbound ditch. The SUV rolled multiple times and came to rest on its passenger side. 

The deputy notified Sedgwick County dispatch and went to assist. By then, the vehicle caught fire under the engine. The deputy found Costello and two children in the vehicle and radioed for EMS and fire personnel. 

The document states the fire was getting worse and the deputy had to climb on top of the SUV to break out a window to attempt to get the children out of the backseat. Costello was trying to get to the children and refused to get out. 

All three were pulled from the vehicle. The 4-year-old girl was unresponsive, and another officer began CPR. One deputy said he could smell alcohol while applying gauze to Costello's neck and while inside the ambulance transporting her.

Costello, her daughter and her 2-year-old son were rushed to Wesley Medical Center in Wichita, where the girl was pronounced dead at 7:39 p.m. Costello and her son suffered non-life-threatening injuries. 

The sheriff's office reported evidence at the crash scene showed the SUV left the roadway to the right and went into the ditch, where it continued for 326 feet and going over two culverts before hitting a third and going airborne. Tire tracks in the ditch showed heavy braking was not applied. 

"Due to the lack of heaving braking to cause skid, using a rolling resistance for the total distance of the Ford in the ditch, the minimum speed that the Ford could be traveling would be 22 miles per hour with absolutely no braking," the affidavit says.

The SUV had become fully engulfed, destroying potential additional evidence. 

The children's father, who had previously been engaged to Costello, told a deputy at the hospital that he and Costello drank vodka straight from the bottle while he was dropping the kids off at Costello's and helping with things around the house. 

Costello consented to a blood draw at the hospital, which was executed just after 7 p.m. She had a blood-alcohol level of .112.

Butler County court records show Costello was arrested for DUI in September 2023, months after her daughter's death. A hearing in that September case is scheduled for June 24.

She also has prior convictions of battery, leaving the scene of an accident, and possession of a firearm while under the influence, all misdemeanors. Charges were filed in that case in November 2021.
