The Robeson County jail, built in the early 1990s, is supposed to hold up to 410 people. As of May, it had a population of 501. Overcrowding has plagued the jail for months, according to records from the state Department of Health and Human Services. Sheriff Burnis Wilkins said he has had to buy cots and extra blankets because there aren’t enough beds. State inspectors have ordered the jail to reduce its numbers.
