Shreveport police spokesman Bill Goodin tells The Associated Press that investigators believe they know who the suspect is and are obtaining a warrant for his arrest.
Goodin says a news conference will be held at 9:30 a.m. CDT to outline details of the deadly shooting and release the name of the dead officer.
Clp. Marcus Hines said late Wednesday that the officer was shot while responding to a report of a suspicious person inside a home. Hines says an armed man was apparently inside the home, threatening to harm people.
Goodin says Shreveport police, Caddo Parish deputies, along with DeSoto Parish deputies and the state police are searching for the shooter.

Grover D . Cannon
Police are now searching for Grover D. Cannon in connection with the fatal shooting of an officer last night.
Cannon is also wanted in connection with a shooting that took place July 15.
A Shreveport police officer was shot and killed in the line of duty Wednesday night.
Early a.m. Thursday update:
A Shreveport police officer answering a Wednesday night call was gunned down.
Agents from across the region descended on Queensborough after a 9:14 p.m. call became fatal. Midnight came and police had made no arrest despite more than 70 units called to the scene, backed by helicopters and drones.
Police came to Del Rio Street's 3500 block on a suspicious person call. They expected an armed man inside a home threatening a family member.
When police arrived, someone opened fire. The officer was hit several times and was taken to University Health but died.
Police had not named their lost officer by 12:30 a.m., nor was the shooter captured.
Police locked down Queensborough with help from Bossier City police, sheriff's deputies from Caddo, Bossier and DeSoto, the U.S. Marshals and the Louisiana State Police. They were all hunting whoever fired the killing shots.
Responding officers were intent on capture and clearly anguished. Police expected a long night.
The perimeter from the scene was one square mile wide. Bystanders were ushered out of the immediate area and into a supermarket parking lot. At 12:30 a.m. police were investigating a house Judson Street, but quickly confirmed the shooter was not inside the home.
Shortly after the inquiry on Judson Street, police began investigating an abandoned home on Lakeshore Drive near Jewella Avenue. Caddo Sheriff's Office's tactical force unit joined officer in front of the residence around 2 a.m.
With all eyes, lights and barrels pointed toward the dilapidated home, SWAT approached the front door and, following three verbal warnings, forced entry into the residence.
However, a full sweep of the home by SWAT and K9 units revealed the shooter was not inside. In just moments the tense scene broke and dispersed.
43 units remained on the scene as of 4 a.m.
[Late Wednesday update:]
More than 70 law enforcement units responded after 9 p.m. to a call in Queensborough, where the incident occurred.
According to Shreveport Police Department spokesman Cpl. Marcus Hines, the department received a call at 9:14 p.m. about a suspicious person at the 3500 block of Del Rio Street. Hines said a man inside a home on the block was armed and making threats toward a family member.
Hines said when an officer arrived on scene, the subject opened fire.
The officer was taken to University Health in Shreveport with "critical injuries." The department confirmed to The Times just after midnight that the officer died from his wounds.
Helicopters also were being used in the manhunt.
Officials would not identify the officer and did not provide a detailed description of the gunman.
A Caddo Parish constable's office posted on its Facebook Wednesday night: "May God bless the family of the SPD officer that lost his life tonight serving our city. Please keep this officer's family in your prayers tonight as well as our local law enforcement. He died protecting us.''
Shreveport Chief Willie Shaw said the department will host a press conference Thursday.
Over the past 130 years, almost 50 firefighters and police officers have lost their lives in service to their communities
