A chase late Monday of an alleged robber along La. 1 in West Baton Rouge Parish led to a standoff and to the fatal shooting of the suspect by an Addis police officer, State Police said.

Brusly police received a call around 6 p.m. about a masked gunman running into Noah’s Pharmacy in Brusly, Trooper 1st Class Jared Sandifer said. Troopers were called about the incident at 6:07 p.m., he said.

Brusly police called Addis police for backup, he said.

Police believe the alleged robber realized authorities were coming, so he took a female cashier at the pharmacy hostage and stole an Addis police car, Sandifer said.

The man forced the hostage to drive the police car as authorities chased them down La. 1, Sandifer said.

The car wrecked at La. 1 near the Intracoastal Waterway bridge, Sandifer said, with the car ending up in a ditch. After the wreck, authorities and the suspect got into a standoff as the suspect threatened to shoot the hostage and officers, Sandifer said.

An Addis police officer eventually shot the alleged robber, Sandifer said.

The hostage was taken to a Baton Rouge hospital with minor injuries, Sandifer said.

The chase caused multiple other car crashes, but no one was injured, Sandifer said.

Brusly police and the Sheriff’s Office will investigate the robbery, and State Police will investigate the crashes and shooting, Sandifer said.
