ORLANDO, Fla. (AP) - A central Florida man sent distraught text messages to friends before fatally shooting himself at a gun range and allegedly killing a 21-year-old woman.

Worried friends called Orange County sheriff's deputies Saturday after receiving suspicious text messages from 24-year-old Ryan Ray Scurlock. As deputies were checking his residence, they realized the shooting victim at a nearby gun range was Scurlock. Authorities believe Scurlock shot himself.

Other calls led deputies to a second crime scene where they found the body of Jennifer Lynn Roqueta inside an apartment. Deputies did not say how she died.

Authorities believe the deaths were part of a murder suicide plot.

Scurlock's death is the latest in a string of suicides at area gun ranges.
