According to the Lake County Sheriff’s Office, while Tramble was in jail on felony home invasion and domestic battery charges, detectives learned he was trying to contact a hitman to kill a witness who planned to testify against him.

“Witnesses should never fear for their safety or be intimidated into not testifying,” said Sheriff John Idleburg in a press release.

Tramble later reached out to someone he believed to be a hitman but was actually an undercover sheriff’s detective. Following an investigation, Tramble was charged with solicitation of murder for hire.

Tramble is being held on $500,000 bail. His next court date is March 14.
