Police said a father and son were arrested Friday after investigators found drugs, moonshine and bomb-making materials in their Oviedo home.

Police raided the Oviedo home of father and son Robert and Matthew McKissic early Friday morning.

Investigators went to the seemingly ordinary home with a search warrant after they got a tip from a neighbor. When they got there, they made a bizarre discovery. They found cocaine and drug paraphernalia used to make crack cocaine, a pipe bomb, other bomb-making materials and even a still used to make the moonshine and 10 gallons of moonshine.

WFTV's Kenneth Craig spoke with people who knew the family.

"That's crazy. You never know what somebody's doing next door. You never know who's living next door," said a neighbor who wanted to remain anonymous.

Several neighbors told WFTV they noticed constant traffic at the house and other strange behavior, but said they didn't suspect this.

"That's crazy. I don't believe that. I have to see that for myself," said Erick Reyes, the McKissic's family friend.

Neighbors said the house was always surrounded by cars, and that people were literally counting cash in the driveway. They also said they saw people knocking on the garage door to get in.

Robert McKissic was arrested on charges of possession with intent to distribute cocaine, possession of drug paraphernalia, possession of an explosive device and possession of bomb-making materials.

Matthew McKissic faces misdemeanor charges for possession of marijuana and drug paraphernalia, according to police.

Both men were transported to the Seminole County Jail.

The illegal still and suspected moonshine were turned over to agents of the Florida Department of Business and Professional Regulation Division of Alcoholic Beverages and Tobacco (ABT) to investigate and file the necessary charges.

The Seminole County Sheriff's Office EOD was notified and responded to the scene. The EOD deputies tested and collected the explosive materials and safely removed them from the property. The FBI was also notified and will also follow up with an appropriate investigation.
