Citing the criminal complaint in the case, KSTP-TV, the Star-Tribune, and KARE 11 all report that a friend of Thaler's spoke to detectives, and allegedly said that the young mother had expressed an interest in learning how to use a shotgun. The friend told police Thaler had purchased a shotgun in mid-March, the complaint alleges, according to the reports. The two had visited a gun range over two days, so she could learn how to use the weapon, the complaint alleges. Police allege Thaler would conceal the weapon in a gray blanket whenever she left her apartment with it. A gray blanket was recovered from the trunk of Thaler's car, where Eli's body was also discovered. Minn.

The boy, who wanted to be a firefighter, was previously in the custody of social services, after Dakota County filed a Child in Need of Protection or Service petition on his behalf back in January 2021. Eli spent 457 days between county custody and family foster care. According to a GoFundMe campaign organized to help pay for Eli's funeral, the boy spent 11 months living with extended family members, but in December 2021, a judge allowed Eli to return to his mother's care for a home trial. "Due to many red flags Eli's mother was showing, Tory tried extremely hard to get custody of Eli," the fundraiser's description alleged. "Numerous parties made many statements to CPS, fearing that mom would harm Eli if full custody were returned. Sadly, full custody was returned on May 10, 2022." A judge set Thaler's bail at $2 million. It wasn't immediately clear if she had retained an attorney or entered a plea.
