Police say Winn had a blood alcohol concentration of .16 percent when he lost control of his Dodge Ram at about 3:00 Saturday afternoon, May 25.

He pleaded guilty Monday afternoon to aggravated vehicular homicide, reading to the court exactly what he did that day.

"I left my lane of travel and crashed the truck into the driver's side of a black Cadillac which was stopped at the intersection," Winn said. "As a result of my intoxication and reckless driving, I caused the death of John Heneghan and Caitlin Holtzman. I also caused serious physical injury to Luke O'Doherty, and Julia Staples."

Judge Jim Murphy is expected to sentence Winn to 6 and 1/3 to 19 years in prison as part of a negotiated plea agreement.

Winn remains free on $300,000 bond until his November 21 sentencing.
