Montgomery County police on Sunday identified Roosevelt Brockington, Jr., 40, of Lusby, Md., as the Suburban Hospital employee slain at the hospital Saturday.

According to police, the Calverty County resident had worked at Suburban since August 2006.

Police say they "do not have any suspect description to release" at this point.

The incident prompted a four-hour lockdown Saturday at the medical center's Bethesda campus.
