LAPLACE -- One man died and two others were arrested after the robbery of a high-end clothing store in Metairie and the police chase that followed.

According to police, two men robbed Jeff’s Haberdashery in Metairie around 10 a.m. Wednesday, armed with a military-style rifle. Two employees and one customer were inside the store at the time.

Through witness interviews, JPSO was able to develop George Simon, a LaPlace resident, as a suspect.

A member of the St. John the Baptist Parish Sheriff’s Office, who is assigned to the US Marshals Task Force, began watching Simon’s house in an unmarked vehicle.

When Simon, along with two other suspects, got into a car and left the house, the St. John detective called for backup and followed them.

Officers attempted to conduct a traffic stop, but as officers approached the vehicle the driver accelerated and almost hit two officers, according to Jefferson Parish Sheriff Joe Lopinto.

Police followed the suspects onto I-10 where, after sideswiping several other vehicles, the suspects crashed their vehicle into an 18-wheeler that was stuck in traffic due to a previous accident, according to Lopinto.

All three suspects then got out of the car and jumped over the guard rail. Lopinto approximated that it was a 30-foot fall.

Simon and another suspect, Tahjavon Boatmon, took off running, but the third suspect, Ron Walker, was so injured that he couldn’t keep going and police arrested him at the scene of the crash.

Walker, 53, later died at the hospital.

Simon and Boatman were arrested after a brief foot chase.

According to Lopinto, Simon confessed to planning and committing the crime along with Walker. Boatmon, Simon’s stepson, was not present at the robbery according to Lopinto.

Most of the stolen merchandise was located in the car, but police say there is an ongoing investigation to find the rest.
