Betty Massey was asleep in her Big Pine Key mobile home Saturday morning when she awoke with a gun in her face.

"They were asking where the money was," she told The Citizen Monday.

The grandmother of Franklin Joaquin Randleman Jr. didn't know her grandson had just been shot in the stomach during the apparent home invasion. Paramedics later would pronounce the 18-year-old dead at the scene.

Massey was surrounded by friends and neighbors Monday at the Seahorse RV Park on Big Pine Key. They were helping her move out of the trailer.

Massey, owner of the Crazy Fish Bar Grill, thought there were two invaders, but she said she couldn't be sure.

The Monroe County Sheriff's Office has ruled the case a homicide. It "could possibly be drug related" and "is not believed to be random in nature," said Detective Mark Coleman.

"There was evidence taken from the residence, but I'm not prepared right now to say what that evidence is," Coleman said.

Massey said she was not aware of any drugs in the house. She declined to comment further.

A report of a shooting came in about 4 a.m., and responding deputies arrived to find a vehicle in the driveway with a car alarm going off and the trailer front door open, according to a heavily redacted incident report.

Two deputies entered the trailer with their guns drawn and heard Massey scream, "Help me, please. Save my grandson," reports say.

Randleman's body was found in a bedroom. He apparently had been shot multiple times. First deputies, then paramedics, tried unsuccessfully to revive Randleman, according to the report.

Detectives are following up on leads, but were unwilling to comment on those leads or possible suspects they might have, said Sheriff's Office spokeswoman Deputy Becky Herrin.

Coleman said investigators had not "positively identified" a suspect.

The shooting sent shock waves through the small RV park as neighbors mulled about Monday wondering about a possible motive.

Mark Johnson, a disabled Vietnam veteran who lives about 15 feet from where the shooting occurred, didn't see or hear anything Saturday, he said. Neither did he notice anything out of the ordinary in the past few weeks, he said.

"I never saw any drug activity or anything like that," Johnson said. "I woke up to the flashing lights and somebody said Junior was shot. I couldn't believe it. He always seemed like a nice kid to me -- really happy guy who was always smiling."

Daniel Blanco, who lives directly behind Massey's trailer, said Randleman often helped him work on his trailer.

"He really helped me out fixing up my place," Blanco said. "He kept me company all the time. He's the one who really pushed me to fix my place up. He was a helpful, cool kid. I can't believe it."

Blanco said Randleman was "turning his life around," and was most recently working on starting his own construction company.

Randleman was last arrested on March 12 for misdemeanor failure to appear in court. He has an extensive juvenile record going back to at least 2008, but no drug charges, records show.

In 2008, Randleman was arrested for fleeing police, having no driver's license, vehicle theft and resisting arrest. In 2009, he was charged with six counts of burglary, four counts of theft, grand theft, criminal mischief, dealing in stolen property, hit and run and driving with a suspended license.

Detectives ask that anyone with information about the case call them at 305-289-2410.
