According to officials with the Clay County Sheriff's Department (CCSD), Sankey Rust, 32, Brazil, remains at-large.
Sheriff Mike Heaton informed The Brazil Times his department has received some leads on Rust's whereabouts, but have been unable to find him.
"We had one location called in," Heaton said. "It was checked out. Everybody involved (in the initial investigation is searching)."
Heaton added the U.S. Federal Marshal's Fugitive Task Force is also actively searching for Rust.
As of Thursday, Heaton said the overwhelming belief was that Rust was still in the area.
"There is speculation that he may have (left the area)," Heaton said. "But at this point, we're just unsure."
Chief Deputy Rob Gambill agreed.
"It's a possibility that he may have left the area," Gambill said. "I feel that there is a good chance that he is still here. But then again, it wouldn't surprise me if he was picked up (in another state).
"At this point, he is certain we are after him. He knows what he may be facing. Local officers are looking. We're knocking on every door and checking every location that we get a tip on."
Gambill added Rust has a history of using firearms and should be considered armed and dangerous.
"Anytime somebody has a history of firing a gun during a crime, it is taken seriously," Gambill said. "We try to make contact with this person to try to avoid any incident."
Officials stated Rust has a long criminal history, stemming back to an armed robbery incident in 1998.
"We've arrested him in the past," Gambill said. "He's been violent with others."
A $1,000 reward has been issued through the Wabash Valley Crime Stoppers for information leading to Rust.
