PROVO, Utah (Court TV) — A Utah woman faces life in prison after she was convicted of masterminding a plot to kill her son-in-law, who was shot to death in her home.

Tracey Grist, 60, was convicted of murder, criminal conspiracy, obstruction of justice and domestic violence in the presence of a child in the death of Matthew Restelli, 42. Matthew Restelli was shot to death in Grist’s home at the hands of Grist’s son, Kevin Ellis. Her sentencing is scheduled for June 10.
Matthew Restelli’s wife, Kathryn Restelli, who is Grist’s daughter and Ellis’ sister, pleaded guilty shortly after her arrest to murder, conspiracy to commit murder and discharge of a firearm. She was sentenced to one to 15 years in prison.
Prosecutors said that Matthew Restelli was lured to his death, believing he was arriving at Grist’s home to pick up his wife and two children and return with them to their home in California. But Kathryn Restelli testified that she had no intention of leaving and instead worked with her mother and brother to kill the victim.
Ellis told police that he shot his brother-in-law in self-defense and pointed the police officers on the scene to a knife in Matthew Restelli’s hand. But investigators determined that the knife was in his non-dominant hand — and the knife in question had been purchased online, allegedly by the defendant. The jury determined, as part of their verdict, that Grist was a party to planting the knife in the victim’s hand and that she made untruthful statements to 911 when she called them and said that her son-in-law had been armed.
At Ellis’ sentencing, prosecutors said that they considered Grist to be the ringleader of the plot and have pointed to digital evidence they say ties the matriarch to Matthew Restelli’s killing. Among that evidence is Grist’s search history, which included searches for “Katherine Magbanua,” a key player in the murder of FSU professor Dan Markel. Grist took the stand in her own defense and claimed that she had made those searches out of curiosity after listening to a true crime podcast.
Markel was killed in a murder-for-hire; five people have been sentenced for his death, including his former mother-in-law, Donna Adelson, and former brother-in-law, Charlie Adelson. “Where was Donna Adelson arrested?” as well as a search for a “Dateline” episode focusing on the Adelson’s family also appeared on Grist’s devices. Grist also allegedly searched for “how to get my U.S. passport fast,” and for the “it’s happening meme.”
