Former Windsor Locks police sergeant testifies in own defense

WINDSOR LOCKS, CT (WFSB) -

A Windsor Locks police officer accused of trying to cover up evidence in a deadly crash involving his son took the stand Friday.

"I was walking down there," said Robert Koistinen, who is charged with hindering prosecution. "I observed my son standing in middle of the road."

A former Windsor Locks police officer, Michael Koistinen was sentenced to five years in jail after pleading no contest to manslaughter and tampering with evidence for hitting and killing Henry Dang.

Police said Michael Koistinen was driving more than 70 mph in a 35 mph zone when he hit the Windsor Locks High School sophomore, who was riding his bicycle at the time of the accident.

"Upon noticing my son, I looked at the car and was like 'oh my God, that's our car,'" Robert Koistinen said. "Mike was upset, so I asked him to have a seat in the back of the police vehicle."

Robert Koistinen was the first responding supervisor on the scene that evening in October 2010. He said he called the police chief and regional accident reconstruction team because a family member was involved in the crash.

"I felt the incident of this nature, there was going to be a lot of controversy and scrutiny so get NICMARS in there as soon as possible to alleviate any doubt or suspicion in anyone's mind," he said. "I then returned to my vehicle and directed traffic."

A witness previously testified that Michael Koistinen threw a beer glass from the car after the crash. Robert Koistinen told prosecutors that he never asked his son if he threw the glass or had been drinking that night.

"He told me, 'I do not what happened dad, he came out of nowhere,'" Robert Koistinen said. "He was upset, crying at times."

Both Koistinens have been fired from the Windsor Locks Police Department.

Dang's family was in the court as they were for Michael Koistinen's trial. However, they did not want to comment until after the case was complete.

The defense rested its case Friday. The closing arguments are set to began on Wednesday.

Michael Koistinen is expected to serve 64 months of the sentence.
