LA CROSSE, Wis, (WKBT) -

A hearing is set for April 7 for Eric Koula as he and his attorneys appeal his homicide conviction.

Koula is serving a life sentence for killing his parents at their home in 2010.

In the appeal, Koula's attorneys say the judge wrongly excluded evidence and gave the jury unclear instructions regarding testimony made outside the courtroom.

The La Crosse County D-A asked for the appeal to be thrown out.
