(KMOV) -- Authorities have arrested a Lincoln County man accused of assaulting his grandmother Monday night.
According to investigators, Mark Kerpash flew into a rage and threatened to kill his 87-year-old grandmother after she refused to write him a $500 dollar check.
The woman eventually under duress wrote the check after Kerpash allegedly assaulted her in her home on the 4000 block of Highway 47 in Hawk Point.
Police say Kerpash then fled the scene in a light blue vehicle with a female passenger, later identified as Jennifer Coleman, 27, before officers arrived.
Residents took to the sheriff's office Facebook page with leads on possible whereabouts of Kerpash and Coleman. Deputies later learned the two may still be in Lincoln County.
“By Wednesday, we knew, through Facebook posts and personal conversations shared by concerned citizens Kerpash was in the Troy or Hawk Point area,” said Sheriff Cottle. “Kerpash’s desperation to leave Lincoln County was evident when he started accepting help from social media acquaintances who were not considered actual friends. If it was not for the help and trust of our citizens, I do not believe we would have apprehended Kerpash as fast as we did.”
Kerpash and Coleman were captured late Thursday night at a Winfield residence.
They are being held at the Lincoln County Jail facing felony charges of first- degree elder abuse, first-degree robbery, first-degree burglary and financial exploitation of an elderly person.
Kerpash was refused bond and Coleman’s bond is currently set at $500,000 cash only.
