Lenny Fuchs, 36, Laura Leong, 30, and Zeeshan Mohammed, 27, killed and driver Praneeth Manubolu arrested in collision on Park Loop Road in Acadia National Park in Hancock County, Maine

Three people died after their vehicle rolled over early Saturday morning in Acadia National Park. The crash was reported around 3 a.m. Saturday, according to the National Park Service on the one-way section of Park Loop Road.

After Manubolu called 911 to report the crash at 2:47 a.m. Saturday, investigators arrived at the crash site on Park Loop Road to find that he had some cuts and scrapes and allegedly smelled of alcohol, according to an arrest affidavit written by U.S. Park Ranger Brian Dominy.

Following his release from the hospital, Manubolu was arrested and taken to the Hancock County Jail in Ellsworth.

Manubolu was indicted Wednesday on three counts of manslaughter, two counts of operating a motor vehicle under the influence of alcohol or drugs, and one count of unsafe operation.

The U.S. Attorney’s office argued in a response filed in federal court in Bangor that a blood sample from Praneeth Manubolu, 28, was legally obtained in the hours following a fatal crash in the park over Labor Day weekend — even though Manubolu refused a request from police to submit a sample voluntarily.
