LINCOLN, Neb. (AP) — A legislative panel says Nebraska needs to do a better job tracking mental health data for inmates and the amounts of time that inmates spend in segregation.

The committee said in a report Monday that mental health information for specific inmates is not always up to date. The Performance Audit Committee also says it’s impossible to calculate how much total time some inmates have spent in segregation.

Sen. John Harms of Scottsbluff, the committee chairman, says the Department of Correctional Services should submit to an independent audit of its electronic data system.

The review was prompted by the case of Nikko Jenkins, an inmate who was released in 2013 despite begging for mental health treatment. Jenkins later killed four people in Omaha.
