(NewsNation) — Authorities are no closer to finding Kentucky shooting suspect Joseph Couch, 32, and continue to hope he will come out of hiding and give himself up.

Kentucky State Police Trooper Scottie Pennington held a press conference Tuesday afternoon to provide an update on Couch, who is on the run in southern Kentucky woodland.

Couch is accused of shooting at 12 vehicles on Interstate 75 in Kentucky on Saturday, which injured and wounded at least five people.

The former Army Reserve member has been on the run since the shooting. Pennington asked for patience at Tuesday’s press conference.

“This is not like going across the road and looking in the woods and finding somebody,” Pennington said Tuesday.

“This is the national forest. This is 1000s and 1000s of acres…. and we have no evidence at this time that Mr. Couch has left there,” he added.

Pennington pleaded with Kentuckyeans to keep sending in tips, hoping they would assist in Couch’s capture.

Authorities are patrolling the Rockcastle River area where Couch is expected to be hiding, but the terrain is challenging. Pennington described the land being searched as a jungle.

“Our main focus is to remain in those woods until we find him,” Pennington said. “We’re going to stay in the woods until we find him. If he’s dead or alive, it’s our job to find him.”

The FBI, ATF, and Kentucky State Police are all involved in the search. He was not previously familiar to the Laurel County Sheriff’s Office.

While law enforcement has yet to release the names of the victims, they are all expected to survive. An initial $5,000 reward had been offered for information relating to Couch. It has now been increased to $25,000.

Couch became a person of interest after authorities found an SUV registered to him in the vicinity of the attack on I-75.

Pennington has urged residents to be vigilant, check on their neighbors, and avoid hunting in areas near the police search.
