Kansas soccer field crash raises red flags for former investigator who questions key theories

"Law enforcement certainly needed to do a better job as to describing why these charges haven't been filed," says Jamie Copenhaver.

Copenhaver, a former sheriff's detective in Florida who worked with an FBI Joint Terrorism Task Force, is curious as to why law enforcement has been tight-lipped about the lack of charges in the horrific Kansas soccer field crash.

A mother walked away with no charges after investigators say she drove onto the active field at Stryker Sports Complex where children and families were present — killing two and injuring several others.

It happened on Saturday; Cole Adrian, 6, and Nicholas Schafer, 35, who were both from McPherson, were killed. The woman behind the wheel was by investigators that day.

Wichita Police said she was released "pending the results of toxicology testing and a mechanical examination of the vehicle."

Police said in a statement Tuesday that they have interviewed nearly 50 witnesses, with more interviews ongoing. 

"Investigators are also inspecting the truck, analyzing available vehicle data and continuing investigative work at Stryker Sports Complex," police said. "They are working closely with the Regional Forensic Science Center and awaiting official, peer-reviewed toxicology results."

The driver remained at the scene and has been cooperative, they said.

"Based on the information available Sunday morning, and after consultation with the Sedgwick County District Attorneys Office, investigators did not have probable cause to arrest the driver. She was released, and the investigation remains ongoing. Her release does not represent a final determination about whether criminal charges are appropriate."

"We know that this case has captured the attention of people all over the country, and many of those people have strong opinions about the incident even though they do not have direct knowledge of what occurred," Chief Joe Sullivan said. "We recognize that the decision the law and constitution required us to make on Sunday morning may not be popular. We swear an oath to support the laws of the State of Kansas and the Constitution of the United States and no one in the Wichita Police Department takes that oath for granted."

The driver had a valid drivers license and no outstanding arrest warrants, police said. 

They dispelled rumors circulating online, noting that the driver is not in the country illegally, has no documented criminal history, and no association with the Wichita Police Department, the Sedgwick County Sheriffs Office or any other law enforcement agency. 

Andrew Ford, a spokesperson for the Wichita Police Department, told TMZ that the driver was interviewed for several hours after the crash. He said she answered questions about what happened, according to the outlet.

Ford told TMZ that police are investigating all possibilities about why this happened, including whether speeding, mechanical failure, or drugs or alcohol played a factor.
