A man arrested in Marshall County last week following a high-speed pursuit has now been charged with murder in connection with the disappearance of a Florida man.

Robert Paul Lanning III, 28, of Melbourne, Fla., now faces charges of first degree felony murder and grand theft motor vehicle out of Palm Bay, Fla., a city of almost 120,000 on the state’s mid-Atlantic coast.

Lanning was arrested Sept. 5 following a vehicle pursuit on U.S. 431 that began in Marshall County, extended into Madison County, then doubled back into Marshall before ending in a collision in Guntersville.

Lanning was transported to Huntsville Hospital, where he remained in custody of the Marshall County Sheriff’s Office until he was released on Sept. 7, according to Marshall County Sheriff Phil Sims. He is currently being held in Marshall County Jail on charges of attempting to elude and fugitive from justice.

Lanning was found to have a felony probation warrant from Jackson County, Ga., but authorities there declined to extradite him.

However, on Sept. 7, investigators with Palm Bay police Florida contacted Marshall County investigators to let them know Lanning was a person of interest in a missing person case in their jurisdiction.

The vehicle that Lanning had been driving, a white BMW, was registered to a missing person, Nicholas Mitchell 30, of Palm Bay.

Officials from Florida located Mitchell’s bullet-ridden body on Sept. 8. Lanning’s girlfriend, Rene Lemos, 41, was located in Kennesaw, Ga., and taken into custody on charges of being an accessory after the fact to first degree felony murder and grand theft motor vehicle.

Lanning will be extradited to Florida to face his charges, Sims said.

According to WFTV in Florida, both Lanning and Lemos said they met with Mitchell on Aug. 30 at a Circle K convenience store in Palm Bay. From there, they drove to a remote location known as “The Compound” where the shooting happened, and left the body, according to WESH.
