The Ankeny Police Department and Iowa State Patrol are refusing to release speed data and dash camera footage of an accident involving an Ankeny police officer , claiming the information was part of a law enforcement investigation and exempt from public disclosure . Peter Roeder spent two months in a Des Moines hospital recovering from the injuries he received when his pickup truck was broadsided by a police car on June 1 . Officer Jeffrey Davis was driving south on South Ankeny Boulevard when he ran a red light at Southeast Third Street and struck Roeder ' s truck near the driver ' s side door , according to a State Patrol accident report . The collision redirected Roeder ' s white pickup onto the curb , where it struck a tree , smashing in the front grill and bringing it to a stop . Roeder , 62 , suffered a head injury , fractured shoulder and pelvis , collapsed lung and torn diaphragm . Eleven ribs on his left side were crushed . He spent 20 days in the Iowa Methodist Medical Center intensive care unit before moving to the trauma unit . He was released July 30 . The Iowa State Patrol , which investigated the accident , found that Davis had his lights and siren activated when he ran the red light . Roeder failed to yield for an emergency vehicle , according to the report . No charges were filed against either driver . The State Patrol has refused to say how fast the officer was driving , and the Ankeny Police Department and State Patrol have both denied requests for dash camera footage from the officer ' s patrol car . They ' re not required under law to be released , Ankeny Police Chief Gary Mikulec said . Iowa law enforcement agencies have increasingly withheld information from reporters and the public , citing a controversial and relatively recent interpretation of a 45 yearold state law . The new interpretation holds that any document created or collected as part of an investigation can be considered confidential forever . Mikulec referenced the investigative file exemption when denying The Des Moines Register ' s request for dash camera footage . The Department of Public Safety has frequently cited that rule when denying records requests . A Register investigation in September showed the agency denied all or parts of 40 out of 59 record requests it received during the first six months of 2016 . And of the 40 denials , 28 were based on the investigative file exemption regardless of whether the case was closed or remained under investigation . Iowa Department of Public Safety spokesman Alex Murphy told the Register at that time that the department ' s general policy is to withhold information related to investigations unless it fits the immediate facts and circumstances of a case , which Iowa law generally requires to be released . Sgt . Nathan Ludwig , a spokesman for the Iowa State Patrol , echoed that statement when denying the Register ' s request to release the speed of the officer ' s vehicle , saying the vehicle ' s speed was not an immediate fact and circumstance of the accident , and therefore would not be released . The speed limit is 35 mph along that stretch of South Ankeny Boulevard . The Ankeny police officer was responding to the pursuit of an ATV near Northeast 36 th Street and Interstate Highway 35 , about 3 miles northeast of the crash site . Earlier in the day , an ATV driver damaged a corn field in a same area and ran from police when they began chasing him .
