After two-and-a-half months on the run, a Livingston Parish fugitive was arrested in Texas on Saturday for robbery, aggravated battery and failure to register as a sex offender, authorities said.

With an outstanding warrant for his arrest, Walker resident Dennis Shampine told police he hitchhiked from Baton Rouge to Beaumont, Texas, where he landed a job at a construction site, Walker police said.

Beaumont police arrested him Saturday morning after they said he choked a coworker at a construction site until the worker was unconscious, stole the man’s money and took off on foot, according to a news release from the Walker Police Department.

When police arrived at the construction site, several of Shampine’s coworkers directed them to the motel where he was staying, the release said.

As two officers pulled up to the motel, Shampine darted into a nearby wooded area where officers chased him for nearly half a mile. He ran across a four-lane highway before officers eventually subdued him with a stun gun, authorities said.

Livingston Parish Sheriff’s Office and Walker police plan to extradite Shampine to Louisiana pending the disposition of the Beaumont case that occurred at the construction site Saturday, the release said.

In the meantime, authorities plan to investigate those who may have helped Shampine while he was on the run from Louisiana, authorities said.

“We have believed from the beginning that Mr. Shampine was receiving assistance from friends and acquaintances who knew of his whereabouts,” Walker Police Capt. John Sharp said in the release.

Additional charges against Shampine are possible, authorities said.
