Overview

• Police say 22-year-old Lowell Tucker Dorn broke into a Mesa apartment before dawn on Sept. 17 and stabbed a mother and her two teenage daughters.
• Dorn is charged with three counts of attempted second-degree murder and one count of first-degree burglary, according to court documents.
• Investigators linked Dorn after a Tempe resident’s home video and online posts flagged a man seen trying to enter a house, with identifiers such as tattoos and glasses aiding the match.
• In interviews cited in court records, Dorn admitted intending to kill, said he had stopped psychiatric medications for months, and reported recent marijuana use he believed was laced with PCP; Tempe police sent him for an involuntary mental evaluation.
• The daughters have returned home, the mother remains hospitalized, the injuries were deemed non–life-threatening, and relatives say the family plans to relocate with community fundraising support.
