New Rochelle fire fighter Keith Morris was legally intoxicated at the time of his death July 23.
Toxicology results released this week by the Connecticut Department of Energy and Environmental Protection shows that Morris had a blood alcohol content level of .25.
In Connecticut, the standard for boating under the influence is .08, according to department spokesman Dennis Schain.
Morris was killed when the boat he was piloting hit a breakwall the night of July 22 near the Stamford Lighthouse in the Long Island Sound. His body was found the following day.
Four passengers in the boat were rescued. They had reportedly been at the Crab Shell, a waterfront restaurant and bar in Stamford, before the accident.
Morris was born on Sept. 29, 1981 in New Rochelle. He was a firefighter with the New Rochelle Fire Department for more than eight years.
