BOSTON -- The Massachusetts State Police admitted that errors were made when a call from an emergency call box went unanswered long enough for a man to be hit and killed by a car.

Team 5's Sean Kelly reported Wednesday that a Methuen woman picked up one along Interstate-93 in Tewksbury on June 30. The call was not immediately answered, and her husband was killed in front of his son.

A dispatcher at state police barracks in Andover heard the alarm for service. Alaina Raucci used the call box to get help changing a flat tire. Her first call reached police at 8:33 p.m., but no one responded for 30 minutes. She called back at 9:12 p.m., but there was still no response from state police.

One hour after the first call for help, Anthony Raucci, changed the tire himself. Police said 35-year-old Ki Yong O had taken sleeping pills. He swerved toward the shoulder, hit and killed Anthony Raucci. His wife and son were watching.

State police took about two months to investigate why none of their patrol officers responded to the call box alarm.

"The desk officer failed to notify the appropriate sector patrol of the request for assistance," police said in a statement. "In this particular case, we did not provide the quality of police service the public should expect from the department. We will take every measure to make sure this will never happen again."

The conclusion of the investigation does not shift criminal blame.

Only one person has been charged with vehicular homicide. He has pleaded not guilty.

State Police are still evaluating the conclusion of their investigation, meaning there has still been no disciplinary action.
