Davontae Dukes killed, Demetrius Jermaine Osborne arrested for premeditated murder in Fort Pierce

ST. LUCIE COUNTY, Fla. - Editor's note: It is not WPTV's policy to automatically name a minor, especially when they have not been charged as an adult. In this case, due to the seriousness of the charges, we have decided to name the individual.

17-year-old Davontae Timmahl Dukes was shot to death shortly before 6pm Saturday just north of Fort Pierce.

St. Lucie County Sheriff's investigators have arrested 15-year-old Demetrius Jermaine Osborne of 2901 Kingsley Drive (just north of Fort Pierce) for first-degree premeditated murder, aggravated assault with a deadly weapon and unlawful possession of a firearm by a person less than 18 years old, according to St. Lucie County Sheriff Ken J. Mascara.

"Sadly, two teen-age lives are lost in this incident, one to the violence of another, and one, if convicted, will be imprisoned for a long time," Sheriff Mascara said. "These two teen-agers had their whole lives ahead of them. All that changed on Saturday."

Osborne is being detained without bond at the St. Lucie Regional Juvenile Detention Center in Fort Pierce.

Dukes and his brother, Jeremiah, were riding a bicycle on North 35th Street when Osborne fired gunshots from the back seat of a white Chevrolet Impala, according to detectives.

The two fled and Davontae Dukes fell near North 33rd Street and Avenue N.

Davontae Dukes was treated at the scene by St. Lucie County Fire Rescue paramedics.

He was transported to Lawnwood Regional Medical Center and Heart Institute of Fort Pierce by ambulance where he was pronounced dead at the emergency room.

Police obtained a description of the car and stopped it at North 16th Street and Avenue M less than an hour after the shooting.

Three youths were in the car, but not Osborne.

After interviewing the three, detectives obtained a search warrant for Osborne's home on Kingsley Drive.

At the home, investigators found Demetrius Osborne and took him into custody for questioning.

Detectives discovered a silver and black pistol matching the description of the gun used in the shooting.

The pistol was found under Osborne's mattress in his bedroom.

Osborne admitted to having the gun, rolling down the window of the car and pointing the gun at the Dukes brothers but denied firing the weapon.
