UPDATED February 6 with a statement from the family of a third Prosper student at the scene of the arrest, which was published Monday night.

Two Prosper Independent School District students are charged with murder after a Frisco ISD student they’re accused of shooting died from his injuries.

Alec Ray Adamson and Mason Enslow Schiller, 17 and 18 years old, were arrested Friday in connection with the shooting and booked into Denton County Jail.

Both suspects live in the Lakes of Prosper neighborhood near Prosper High School.

The victim, 19-year-old David Noel Pleasant of Little Elm, attended Lone Star High School.

Little Elm Police, who responded to the shooting and tracked the suspects back to Prosper where they were arrested, reported Saturday that the charges had been upgraded from aggravated assault to murder.

Bond for each suspect is set at $1,000,000.

A third student, a 17-year-old Prosper High School football player, was at the scene when Adamson and Schiller were taken into custody, but he was not involved in the shooting nor was he arrested or charged, according to a statement by his family published Monday night on social media that has since been removed. One of the boy’s parents contacted Texas Scorecard and said they did not intend the statement to be circulated publicly.

Eyewitnesses identified the boy’s truck as the one that crashed following a police pursuit through the neighborhood. His family’s statement said he responded to a call from one of the suspects, who confessed to him before plainclothes police arrived, prompting the chase that ended in a crash.

“He is in full cooperation with the police and gave a witness statement,” his family said. “He was in the wrong place at the wrong time.”

The Prosper ISD community has been making headlines for months, from shocking revelations in August of a school bus driver’s sexual abuse of two little girls that was hushed up by district officials, to last month’s resignation of School Board President Drew Wilborn following his arrest for indecency with a child by sexual contact.
