OSCEOLA COUNTY, Fla. -- A man, who was one of four people arrested in connection with having an arsenal of dangerous weapons hidden inside a Poinciana home, said the weapons were just a hobby. The four suspects in the case face some very serious charges.

The incident started with a discovery made behind a medicine cabinet and a secret compartment full of weapons. The Bureau of Alcohol, Tobacco, Firearms (ATF) will help Osceola deputies determine what laws may have been broken.

Jett Cramer, his fiancée Gayle Justice, and their friend and roommate William Scott Clark all made appearances on drug-related charges before an Osceola County judge Tuesday.

"Do you understand the nature of the charges against you?" a judge asked.

"Yes sir," responded Clark.

However, the most serious charge Clark faces is for having an explosive device. Deputies found what they described as a bomb and a stash of weapons in a secret compartment in Clark's Osceola County home, including a mortar launcher, mortar shells and automatic weapons.

The explosives were found during the course of a marijuana investigation. None of the weapons found on Nicholas Court appear to be stolen and Clark, who described himself as a hobbyist, told deputies he has a Florida concealed weapons permit as well as a federal permit to own automatic weapons. Eyewitness News learned owning fully automatic weapons are legal under certain circumstances.

"There's a very vigorous background check done by local authorities," said Larry Anderson of Shoot Straight Gun Range.

In a phone interview from the Osceola County jail Tuesday, Jett Cramer said that Clark is a collector.

"It's a hobby, he wouldn't hurt a fly," Cramer said.

ATF is checking on the documentation Clark provided on the weapons confiscated by the sheriff's office.

"So we smoke a little pot, we're not bad people," Cramer said at his first appearance.

However, for the ATF, the possession of an explosive device is another matter all together. Except under the rarest of circumstances, it is against the law to own an explosive device.

Cramer said the situation has been blown out of proportion.
