Heike Poike was 50 when she was killed on September 18, 2015, in a Salt Lake City home on Sir Philip Drive. Officers performed a welfare check after school staff reported that Heike hadn’t picked up her 8-year-old grandson. Responding officers found the front door unanswered, a tarp visible through a window, and the back door ajar. Inside the residence they discovered Heike, her 2-month-old granddaughter Lyrik Poike, and a 28-year-old man, Dakota Smith, each shot multiple times.

Police located the homeowner, 32-year-old Alexander Hung Tran, in the basement; he surrendered and told officers he was putting down his gun. Tran rented the upstairs unit to Heike’s family and lived in the basement. Investigators say Tran had developed an obsession with Heike’s daughter, Ashley Poike, who had recently moved into the house with her children; prosecutors say Tran sent escalating texts to Ashley and later told police he shot the three victims because they wouldn’t move out after his mother, the homeowner, told him to evict them.

Alexander Tran was arrested and booked on suspicion of three counts of aggravated murder. What can readers add who knew Heike, Lyrik, Dakota, or the household in 2015?
