Christopher Franklin Weaver wore a scowl on his face as he walked among the leaders of a pack of 32 Lane County Jail inmates who were released en masse at 11 a.m. Thursday as part of a budget-balancing plan instituted by sheriff’s officials.

Police say he continued walking for a mile or so, robbed a bank, got caught and was promptly returned to the county lockup.

“This isn’t necessarily a worst-case scenario, but it’s a very bad case,” Lane County sheriff’s Sgt. Carrie Carver said.

Eugene police officers arrested Weaver shortly after the 11:55 a.m. heist at a Pacific Continental Branch at 1450 High St. and handed him over to FBI officials, who took him back to jail.

Weaver, who allegedly presented a demand note to a teller before fleeing with an un­disclosed amount of cash, is expected to face a federal bank robbery charge.

As a federal inmate, he will remain behind bars unless a U.S. District judge authorizes his release.
