History
On September 2, 2003, Alan Scott Johnson and Diane Johnson were shot to death in their Bellevue, Idaho, home. Alan was shot twice in the chest, while Diane was shot in the head. Their daughter, Sarah Johnson, was found guilty of their murder. Sarah was 16 years old at the time. Her apparent motive was her parents' prohibiting her from dating a 19-year-old drug dealer named Bruno Santos.

At approximately 6:20 am on September 2, 2003, Johnson took the murder weapon, a .264-caliber Winchester Model 70 bolt-action rifle from the guest house. The tenant of the house had left for Boise, Idaho, and had not planned on returning for a week or so. She then walked into her parents' bedroom and shot her sleeping mother in the head, whereupon she walked into the bathroom and shot her father in the chest, right above the heart, while he was showering. DNA evidence was presented at trial from a discarded bathrobe and a latex glove that police found in the garbage can in front of the house. It contained the DNA of both victims and Sarah. Along with the robe and latex glove was a leather glove that had gunshot residue on it. In Johnson's bedroom, investigators located the other leather glove that belonged to the pair.

Johnson was convicted of the murders of her parents by an Ada County, Idaho, jury on March 16, 2005. She was sentenced to two concurrent life without parole terms plus fifteen years for a firearm enhancement. The Idaho Supreme Court upheld her conviction.

In 2012, Johnson's lawyer filed a petition for a new trial, charging that she had ineffective legal counsel in the murder trial. They also cited the absence of any blood spatter on Johnson and the fact that fingerprints on the murder weapon matched those of a renter who was living in the family's guesthouse. In October 2014, the request was denied. In 2017, Sarah tried to get her life sentence reduced, citing the Miller v. Alabama and Montgomery v. Louisiana Supreme Court rulings; however, her sentence was upheld.

Johnson is currently imprisoned in the Pocatello Women's Correctional Center.
