Alleged shooter in Lookout Valley triple homicide accepts plea deal

A second gunman charged in the 2014 Lookout Valley triple homicide accepted a plea deal Friday that will send him to prison for 15 years.

Prosecutors have long said Skyler Allen helped his friend Derek Morse shoot and kill three men outside of a trailer home on Kellys Ferry Road on April 9, 2014. They argued Morse was angry one of the victims, Jon Morris, tried to ambush him a few nights earlier over money. Jurors convicted Morse, 23, of first-degree murder and sentenced him to life without parole after a trial in September.

But prosecutors agreed to a reduced sentence for Allen - scheduled to stand trial in April for three counts of first-degree murder charges - because they had a weaker case against him than they did against Morse.
