Attorneys for David Camm filed court documents Tuesday arguing he’s been in prison for 12 years without a fair trial and will remain there for another year unless granted release. The motion argues that being in prison is hurting his ability to prepare for trial.

Camm had been a state trooper for more than a decade, but left the force about four months before his wife, Kimberly, and their children, 7-year-old Bradley and 5-year-old Jill, were shot to death in the garage of their southern Indiana home.

Appeals courts overturned jury verdicts that convicted Camm of murder in 2002 and 2006.
