The Baton Rouge Police Department identified the officer involved in the early Sunday morning shooting of a suspected drunken driver as Matthew Jackson, a five-year veteran of the department, a police spokesman said Monday.

Jackson is assigned to the uniform patrol bureau and is on paid administrative leave pending the outcome of an investigation, Baton Rouge Police Cpl. Don Coppola Jr. said.

The Police Department’s spokesman said he did not know Jackson’s age.

Jackson stopped Derek Davis, 27, of Baton Rouge, for suspicion of drunken driving near the intersection of Glendale Avenue and Morning Glory Avenue just after 1 a.m. Sunday morning. Police have said Davis resisted arrest and ran away from Jackson.

Davis allegedly tried to grab Jackson’s gun while threatening the officer’s life, and Jackson drew his weapon and fired multiple times, hitting the suspect, Coppola said Sunday.

Davis, 10812 Stanley Aubin Lane, Baton Rouge, was taken to a hospital, and Coppola said Sunday night that he was expected to survive. On Monday, there was no update available on Davis’ condition, he said.

Coppola refused on Monday to release information about Davis’ blood-alcohol level at the time of the traffic stop and what counts he may face from the incident, citing an ongoing investigation. Coppola has said Davis will be booked once he is released from the hospital.

“This is an internal investigation that’s being conducted on the incident at hand,” Coppola said.

It’s unknown how long the investigation will take.

“We’ll conduct a thorough investigation and during that time, the officer will remain on administrative leave until that’s completed,” Coppola said.

He said Livingston Parish issued a fugitive warrant against Davis for simple burglary.

Lori Steele, spokeswoman for the Livingston Parish Sheriff’s Office, said in an email Monday that she could not find details of that warrant until the records office opens Tuesday.
