The family of Kaylee Goncalves is livid over the plea deal offered to accused murderer Bryan Kohberger ... and now it appears they're hoping the feds will step in.

The grieving family of 21-year-old Kaylee Goncalves spent weeks waiting for an arrest in her killing. Since then, they and relatives of the three other University of Idaho students fatally stabbed on a late 2022 night in their off-campus home have endured a legal process punctuated by delay after delay.

Kaylee Goncalves' 18-year-old sister, Aubrie Goncalves, is speaking out after her suspected killer, Bryan Kohberger, has reportedly accepted a plea deal.
