Investigators interviewed that girl after a Mankato West High School police liaison officer received a call from a student's father earlier March 10. The father reported he had found text messages on his son's cellphone that he believed could be related to the investigation into Moses' death.
When that boy was interviewed at his house in North Mankato, he told the liaison officer that he had talked to Moses sometime before police suspect that Hafner and Moses used the drugs. She told him she had obtained a powder drug from the 15-year-old boy identified by Hafner.
The North Mankato boy told the liaison officer he also had received a call from the girl who had been at Moses' house with Hafner. He said she asked him for advice because Moses was having a seizure. The boy also said he knew the 15-year-old boy was selling marijuana and LSD. The portion of the complaint describing the North Mankato boy's interview with police does not mention Hafner nor the other girl's grandmother.
On March 11 police searched the apartment complex where the boy accused of selling the drug to Hafner lives. A container with a crystalline powder substance was found in the boy's closet, the complaint said. Investigators also reported finding small blue bags with gold crowns that looked like the ones found during the death investigations.
Hafner allegedly told investigators he and Moses had used LSD once before. He had obtained the drug from the same boy that time, except it was on a small piece of blotter paper, the complaint said.
Jason Bennett, a Mankato detective, checked Hafner's phone and reported finding text messages between Hafner and the 15-year-old boy. A Feb. 28 message from the boy said, "Yeah but that is going to be $20 each. It is really pure/potent. If you want to do two double doses that would be $40, or I can just do five normal size doses for $50."
Hafner allegedly responded saying, "I'll have the double doses."
