MILTON, Mass. (AP) — Norfolk District Attorney Michael Morrissey said Thursday that a four-car crash he triggered in Milton after crossing the center line came after he blacked out following a "medical episode" caused by fatigue, dehydration and the extreme heat.

In a statement, Morrissey said he was driving home from work Tuesday evening when he began sweating and felt lightheaded.

He said the next thing he knew, he was outside his car, which was stopped across the road.

Morrissey said he didn't know what happened until people at the scene "told me my car crossed over the center line causing the accident. I have no reason to dispute that."

Four were hurt in the crash, including Morrissey, who suffered injuries to his hand and torso. Morrissey, 58, was in the hospital the longest and was released Wednesday.

Morrissey said his medical records showed there was no alcohol in his system and that witnesses said speed didn't factor into the crash.

"Instead, my medical records will show that I suffered a medical episode that caused me to lose consciousness and cross over the center line into the opposite lane of travel," he said.

Morrissey was cited by Milton police, but they haven't specified the infraction. A message was left with Milton police Thursday.

"A hearing will be held shortly to determine any criminal liability," Morrissey said in his statement. "It is my hope that this is a speedy process and my intention is to make my medical records available at that time to appropriate personnel."

"This is an unfortunate accident," he said. "I intend to be as transparent as possible in this process."
