HOPEWELL, Va. (CBS19 NEWS) -- Officials say three of four escaped inmates have now turned themselves in to law enforcement.

According to WTVR, Corey Branch and Kareem Shaw surrendered just after midnight Tuesday.

Tavares Lajuane Graham surrendered on Monday.

Now, Lamonte Rashawn Willis of Suffolk is the only one of the inmates who is still at large.

The four men escaped from a federal satellite camp in Virginia over the weekend.

There is a $2,000 reward being offered for information leading to Willis’ arrest.

Officials say none of the inmates were violent threats to the community and most were in custody on drug-related sentences.

The Hopewell minimum-security facility from which the men escaped houses 185 male offenders. An internal investigation is now underway.
