A 15-year-old girl and her 21-year-old boyfriend were arrested after MCSO said they plotted the murder of the girl's father.

According to MCSO, deputies responded to an "unknown trouble" near Buckeye Road and 373rd Avenue Monday. They arrived to find a man, later identified as 59-year-old John Norton, had been shot. He was pronounced dead at the scene.

MCSO said the caller was identified as Norton's 15-year-old daughter. She told MCSO she had witnessed her boyfriend, 21-year-old Daniel Stroh, shoot her father and she fled her home with her little sister.

According to MCSO, after talking with several witnesses and processing the scene, detectives developed a "strong suspicion" that Norton's 15-year-old daughter and Stroh were both responsible for Norton's death.

The 15-year-old initially told police an old boyfriend in his late 20s murdered Norton. Her story began to fall apart when investigators said she told them she didn't call 911 for two hours after the shooting.

MCSO said the two later confessed to the murder, which was allegedly planned several days prior to the shooting.

According to court documents, Stroh told investigators the girl got the gun and gave it to him, telling Stroh to kill Norton or she would, and then kill herself.

Stroh was booked for one count of first-degree murder and one count of conspiracy to commit first-degree murder and tampering with evidence.

The 15-year-old girl was processed into the Durango Juvenile Detention Facility, charged as a minor for one count of conspiracy to commit first-degree murder and one count of tampering with evidence.
