(KEY LARGO, FLA) — An off-duty federal law enforcement officer is dead after he was shot by Monroe County sheriff’s deputies yesterday morning in Key Largo’s Ocean Resort subdivision.

The Sheriff’s Office responded to the residence near Mile Marker 94.8 at approximately 10:42 a.m. on Wednesday where they found Homeland Security’s Lane Caviness armed, drunk and suicidal.

Multiple deputies who responded say they observed a Caucasian male inside the residence and confirmed he was armed.

The Sheriff’s Office was able to reach the man via phone after he moved away from view.

The man stated on the phone he was intoxicated and was prepared to confront law enforcement.

Monroe Sheriff Rick Ramsay says when the 48-year-old pointed an AR-15 rifle at deputies, they shot and killed him.

Deputies began first-aid, but the man was pronounced dead.

The apparent case of suicide by cop is being investigated by the FDLE.
