US Marshals searching for fugitive convicted murderer
A convicted murderer is now on the run after violating his parole. Jonathan James Markle, 46, was convicted of murder and robbery in Bexar County back in 1991.
"On the murder he received a lifetime sentence as well as a consecutive sentence of 40 years for the robbery," said Deputy U.S. Marshal Brandon Filla.
Markle was released on parole in 2008, but this February, he violated his parole by failing to provide a home address, and not appearing to meet with his parole officer.
"It's then when he starts to threaten a family member who resides in Floresville, Texas, and now he has an outstanding misdemeanor charge for terroristic threat," said Filla.
Authorities say someone with Markle's past is a danger out on the streets.
"That is alarming. We do consider him armed and dangerous," said Filla. "I don't know what's in his mindset of threatening a family member, but I know that this murder that he committed in 1991 was somebody that he possibly knew."
Markle is known to have associates in Central Texas from Williamson County down to Floresville. If you have any information on Jonathan James Markle call the Lone Star Fugitive Task Force at 512-800-4213.
