WICHITA, Kan. (KSNW) -- Investigators have released video footage that leads up to a crash that killed a 43-year-old Heartspring worker on Monday. Mandy Buckwalter (Courtesy: Heartspring) The Wichita Police Department said the van that crashed into Mandy Buckwalter's vehicle was stolen and was fleeing. On Thursday, Police Chief Joe Sullivan held a news conference to clarify what happened and to announce the van's driver is charged with murder. He began by offering condolences to Buckwalter's family, co-workers, and loved ones. He then went over the previous details of the case. Sullivan said the stolen van hit a police car as it fled from a Walmart parking lot, and then police decided to end their pursuit for the safety of the public. However, the Kansas Highway Patrol continued to follow the van with its Air Support. Ethics complaint investigation against Mayor Wu will take weeks The KHP shared its video of the aerial pursuit with the WPD. It shows the van leaving the Walmart parking lot and no police cars pursuing it. Sullivan says the video shows the van driving recklessly before the crash. Police stopped the video before the crash out of respect for the family. Sullivan said the video that was shown was released with the approval of Buckwalter's family. Katelyn Barrioz (Courtesy Sedgwick County Jail) Sullivan named the suspect as Katelyn E. Barrioz. He said the WPD presented the case to the district attorney's office Thursday morning, and Barrioz was charged. A Sedgwick County District Court complaint form lists these charges against her: Murder in the first degree, or In the alternative, murder in the second degree Fleeing or attempting to elude an officer Aggravated burglary Theft Criminal damage to property The bond for Barrioz is set at $1.2 million. Her next court date is Nov. 12. Sullivan believes the murder charge is appropriate because the crash was needless. "This person was not being pursued by police. They didn't need to drive this way. No one was pursuing them. They had no idea there were air assets monitoring them. This was an intentional decision that was made to risk the life of any of those cars," he said. As Sullivan continued to detail what happened before the crash, he said a Wichita police officer going in the opposite direction spotted the suspect's vehicle and attempted to turn around. However, Sullivan said the officer did not use his lights or siren and was clearly following orders not to pursue the van. He said police always have to weigh the safety of the community when deciding whether to chase a suspect. "We as a department feel that simply for a stolen auto, that it's just not worth the risk to the public," he said. "But at the same time, the public expects us to address crimes like this that are impacting our community, so we're still going to attempt to apprehend persons driving stolen vehicles. We're just going to use alternative methods." Sullivan said the alternatives include having air support from the KHP, license plate cameras, and officers in unmarked police cars coordinating with each other. He was asked if the WPD would consider changing any of its pursuit policies. "I think actually this incident validates our pursuit policies," Sullivan said. "It's a horrible, terrible outcome, but it's a result of the just terrible choices, intentional choices made by the driver of that vehicle and not the actions of the WPD."
