LINCOLN, Neb. (AP) — Gov. Pete Ricketts says “throwing money” at Nebraska’s prison system may not fix the problems that came to light after two inmates escaped earlier this month.

Ricketts said Monday he’s reviewing a request by lawmakers to approve emergency funding to hire more guards. But he notes that it appears the escape happened because employees forgot to follow security procedures, rather than a staffing shortage.

Nebraska’s corrections department has faced criticism for being short-staffed, with high rates of employee turnover and a large number of inexperienced workers. Director Scott Frakes has said he is working on those issues and will discuss pay with the state employees’ union during the next round of collective bargaining.

Ricketts says Frakes is taking a methodical approach to be a good steward of state tax dollars.
