LA PLATA COUNTY, Colo. — Wednesday is the first of three days of hearings this week for a man accused of killing his 13-year-old son in southwest Colorado nearly seven years ago.

Mark Redwine's trial is scheduled to begin on Sept 19. He's pleaded not guilty to second-degree murder and child abuse resulting in death. 

He's accused of killing his son Dylan in November 2012, shortly after he arrived for a court-ordered visit from Colorado Springs. The boy's remains were found in 2013 and 2015 within 10 miles of Redwine's home near Vallecito Reservoir.

Law enforcement considered Redwine a potential suspect in his son's death since nearly the beginning, but it wasn’t until a review involving outside prosecutors that the local district attorney took the case to a grand jury. 

He was ultimately indicted in 2017 and was arrested in Washington state, where he was driving as a long-haul trucker. His arrest was captured on dash-cam video.

According to the indictment, Dylan's blood was found in his father’s living room, and a cadaver dog detected a scent of a corpse in multiple places in the home.

Dylan's mom spoke following the arrest and said her focus was to move forward and find justice for her son.

"Just sadness. Just - how could you do this to him? It's very overwhelming, the whole process has been very overwhelming," said Elaine Hall in 2017. "But again, I can't change what happened. I can only move forward and be Dylan's voice and continue to fight for justice for my sweet son. "

There have been multiple delays, but now Redwine's four-week trial is set for September.
