EAST NAPLES, Fla.- The Collier County Sheriff's Office is conducting a death investigation that began as a call for service to a disturbance on Lakewood Boulevard at around 11:00 p.m. last night.

Deputies said that when they arrived, they found a man lying in a driveway, bleeding from the left side of his head. The man was later identified as 20-year-old Lonnie Lorenzo Mostiller. A Lakewood Boulevard resident told deputies that Mostiller had just broken into his house across the street.

The Lakewood Boulevard resident told deputies that he and his wife were awakened by Mostiller, who was trying to force his way through their front door while saying, “Help me. Let me in.” When Mostiller was unsuccessful at entering through the front door he crashed through a dining room window and attacked the male resident. Mostiller then jumped back through the window, exiting the residence. He ran across the street and lay down in a driveway.

Mostiller was reportedly agitated and irrational when deputies arrived. He kept trying to stand up despite deputies’ repeated instructions to remain on the ground until EMS could arrive and provide medical treatment. He continued to behave irrationally despite deputies’ assurances that they were there to assist him. When EMS and East Naples Fire Department personnel arrived Mostiller continued to be combative and scream for help as they tried to render aid. For the safety of Mostiller as well as the safety of emergency responders, he was placed in handcuffs. A CCSO deputy accompanied EMS personnel in the ambulance as Mostiller was transported to NCH Downtown Naples Hospital.

He died a short time later at the hospital. All attempts to revive him failed.

CCSO is now conducting a death investigation.
