VAN BUREN COUNTY, Ark. (KTHV) -- A man accused of killing one man and severely wounding another in Missouri has the attention of law enforcement in both in Missouri and Arkansas.

Daniel Campbell's family said they believe an alleged killer is headed our way. According to authorities, Campbell shot two men in Texas County, Missouri Tuesday, killing one and leaving another in serious condition.

"He made a statement to some of his family members there in Missouri that he had a score to settle with someone here in Van Buren County. That's where he was going,” explained Van Buren County Sheriff Scott Bradley.

Bradley has quickly got to work, setting up patrols across the county and getting Campbell's name and face to the public.

"We want to keep everybody safe and get our hands on this guy if he does come in to Arkansas. It helps us to have everyone watching and looking,” he explained.

For two days, authorities have been on the look-out for this black Ford Ranger on a lift kit with green detailing. Campbell allegedly stole it from one of his victims.

Thursday, the Sheriff's office got word someone thought they spotted Campbell in Northern Arkansas in a tan-colored older model sedan with a rusty driver's side fender.

"We've made contact with everybody that he knows here and they are working with us. The person he'd actually made the threat against, we've been working with him to keep him safe." The threatened man's family said they are taking the threat very seriously.

Bradley said Campbell is considered armed and dangerous.

He should not be approached. If you have seen him call 911.
