Authorities in Louisiana said they are looking for a man who escaped after allegedly kidnapping a 73-year-old woman and twice leading authorities in a car chase.

St. John the Baptist Parish Sheriff Mike Tregre told The Times-Picayune / New Orleans Advocate that Aaron Dun, 33, escaped for the second time Friday after crashing a stolen vehicle during a car pursuit with Louisiana State Police in New Orleans.

“Two separate pursuits, two separate cars wrecked and he’s still on the run,” Tregre said. Deputies are asking the public’s help in finding Dun, who is registered as a sex offender with the Birmingham Police Department in Alabama.

State Police in Louisiana first came across Dun on Tuesday while he was allegedly driving a stolen vehicle from Alabama in LaPlace, Tregre said Sunday in a Facebook post. According to Tregre, the driver of the car refused requests to pull over and led deputies in a car chase before he crashed the car and escaped on foot.

That same day, police officers got a call that a 73-year-old woman was kidnapped from her home in LaPlace. When officers arrived at the house, they learned the woman was taken at knifepoint by a man while her 93-year-old mother and a seven-year-old child were present in the home.

Tregre said the man forced the woman into her car and released her after they got to a nearby hotel. He drove away with the car but did not injure the woman, Tregre added.

Investigators were then able to connect the car chase and the kidnapping to Dun, Tregre said.

Dun has outstanding arrest warrants in both Louisiana and Alabama.
