A helicopter that authorities said appeared to be homemade crashed in Florida on Saturday, killing at least two people who were onboard.

The Clay County Sheriff’s Office said the helicopter landed between two buildings on a private property in Clay County around 10 a.m. When they arrived at the scene, officials found the helicopter engulfed in flames and badly damaged.

At least two people who were in the helicopter died, the sheriff’s office said. The victims were not identified.

The flames have since been extinguished. 

It is not clear where the helicopter originated from, and an investigation led by Florida Highway Patrol is ongoing.

Clay County is located nearly 60 miles southwest of Jacksonville.
