SCOTTSVILLE, Ky. (WDRB) -- The son of the man accused of raping and murdering a 7-year-old Scottsville, Kentucky, girl was arrested Monday night -- and police say his arrest is related to his father's alleged crimes.

Twenty-year-old Bradley Madden was arrested for sending threatening messages to the Scottsville Police Department.

On Nov. 21, The Scottsville Police Department received a private Facebook message from Bradley Madden, the son of murder suspect Timothy Madden.

"U got the wrong man u sick [EXPLETIVE] ur have to be missing so ething try harder please don't give up if u book my dad in and he does life u will do life watchi g ur back," he allegedly wrote.

He also allegedly sent this private message: "Go du correctly [EXPLETIVE] u know who I talking about it is a set up from hell when he gets out best belive u will be sued for slander his privacy right and false arrest and yall will go to hell for this."

On Nov. 23, he allegedly sent this private message: "I am coming for you," later posting, "Scottsville look out im coming for everyone whoa has said my name and my fams and my dads so ill meet u there."

Scottsville Police Chief Jeff Pearson called Madden and gave him a verbal warning after the first message.

"I also told him he needed to refrain and not threaten the police department any further," Pearson said. "Or anyone else, for that matter."

When the messages kept coming, Pearson said police took a warrant out for Bradley Madden's arrest, and the 20-year-old was picked up in Tennessee and extradited back to Kentucky.

Chief Pearson says Madden was mad over his father's arrest.

"He cooperated," Pearson said. "He admitted to sending the messages by private messaging through Facebook. His reasoning was he was mad for his father being arrested."

His father, 38-year-old Timothy Madden is in jail, charged with kidnapping, raping, sodomizing and murdering 7-year-old Gabbi Doolin last Saturday at a football game.

Madden told us in a jailhouse interview moments after his arrest that he's innocent.

"It's all Bogus," Timothy Madden said. "I will sue KSP and everyone who slandered my name."

But police say they have DNA evidence against him.

Madden is being held at the Simpson County Detention Center in Franklin, Kentucky, on a $2,500 bond.
