On September 18, 2015, officers in Salt Lake City responded after an eight-year-old boy was not picked up from elementary school and family members could not be reached. Police went to a home on Sir Philip Drive and found three people inside who had been shot to death: 50-year-old Heike Poike, her two-month-old granddaughter Lyrik Poike, and 28-year-old Dakota Smith. The residence was owned by the mother of 32-year-old Alexander Hung Tran, who rented the upstairs to Heike Poike and her grandchildren while living in the basement.

Tran was found in the house in possession of a gun. He was arrested that day and admitted to killing the three victims, with prosecutors alleging the dispute arose over the tenants moving out after the homeowner asked them to leave. Tran was booked on suspicion of three counts of aggravated murder. Legal proceedings were delayed when Tran was diagnosed with schizoaffective disorder and in December 2016 was found incompetent to stand trial and ordered to receive treatment; later developments restored competency and a trial was scheduled.

Did anyone in the neighborhood know of tensions at that household or have information about the days before September 18, 2015?
