VAN BUREN, MO - The reward for information leading to an arrest or conviction in last weekend's slaying of a Missouri state trooper is increased to $30,000.
An anonymous donor has contributed $20,000 to the reward fund in the case of patrol Sergeant Carl "Dewayne" Graham, Jr.
The reward previously had included $5,000 apiece from state troopers groups in Missouri and Illinois.
The unnamed donor gave the $20,000 to the Missouri State Troopers Emergency Refief Society, with the intention that that money be offered as a reward.
Graham was shot to death Sunday outside his home near Van Buren.
He was buried yesterday south of Dexter, his hometown in southeast Missouri.
No charges have been filed in the killing. The investigation continues.
