LAFAYETTE, La. (AP) — The Louisiana Supreme Court won’t hear Brandon Lavergne’s request to overturn his guilty pleas to two murders, including that of 21-year-old university student Mickey Shunick.

His case was among 57 rejected Friday without comment.

Lavergne pleaded guilty to first-degree murder in August 2012, less than two months after his arrest in Shunick’s death. The University of Louisiana at Lafayette student disappeared while riding her bicycle home from downtown Lafayette.

As part of the plea agreement, Lavergne told investigators where to find Shunick’s body in rural Evangeline Parish.

Lavergne appealed in January 2013, saying he felt pressured to plead guilty to Shunick’s death and that of 35-year-old Lisa Pate in 1999 by pretrial publicity and because he faced a possible death penalty.

He’s in prison, serving life.
