Heading into 2017, the most pressing issue facing the Knoxville Police Department is its staffing levels, Chief David Rausch said during a media roundtable Thursday.

The department currently has 376 officers on staff, but it is authorized for 416.

Rausch said they have 51 recruits signed up to start training classes in January, but there are background issues with a few of them.

KPD also expects about five percent of the recruits to drop out after the class.

The department will likely be understaffed until at least June 2017.

So far this year, Knoxville police say they've investigated 14 homicides. Nine of those cases are currently unsolved, but police say they have suspects in six of the cases.
