BRISTOL, Conn. (AP) – An internal investigation has been launched into a complaint that a Bristol patrol captain took his daughter behind police lines to see the wreckage of a crash that killed four teens last month, police said.

Bristol Police Chief John DiVenere ordered the internal affairs investigation after Mayor William Stortz received an anonymous complaint about Capt. Daniel McIntyre’s actions, The Hartford Courant reported Saturday.

McIntyre, who commands the department’s patrol division, acknowledged he brought his 17-year-old daughter behind police lines at the Aug. 23 crash site, where four teenagers died when their speeding vehicle lost control.

McIntyre said Friday that his daughter was one day away from getting her driver’s license, and that he wanted to show her why safe driving was important.

He had worked at the crash scene earlier in the evening and returned with her after his shift was over, he said.

“I was hoping to get across to her the finality of it,” he said. “If my bringing her up there saves her or someone else, then these kids will not have died in vain.”

He said the injured adults in a second car in the crash had already been sent to the hospital, and that he kept his daughter 80 to 100 yards from the wreckage out of respect for the victims and their families.

DiVenere assigned another captain to conduct an internal affairs investigation, but said Friday he thinks whoever submitted the complaint should have approached him rather than sending it anonymously to the mayor.

Four teens were killed in the August crash and three other people were injured when the teens’ car lost control, struck the other vehicle and rolled into a pole.

The teens were identified as the driver, Sean Landry of Plymouth; and passengers, Myles Gosselin, 17, of Burlington; and Jordan Gagnon and Alyssa Roy, both 16 and from Farmington. They had been swimming at a friend’s home before the crash.

The investigation into the crash remains under way, but police have said their initial reviews indicated speed was a factor.
