Brandon James Horst was 25 when he was found dead in his Saint Paul home in the early hours of August 5, 2013. His wife, Heather Horst, discovered him in bed with a head wound and paramedics pronounced him dead at the scene from a single gunshot to the head.

Investigators say what began as a reported home invasion shifted to a plot orchestrated by people close to Brandon. Authorities arrested Heather Horst, 24, and her friend Aaron William Allen, 25, after uncovering a plan to collect about $480,000 in life insurance policies that named Heather as sole beneficiary. Witnesses reported Heather telling Allen that the only way she could be free from her husband was if he were dead. Prosecutors say Heather left a gun on the dining room table, created an alibi by going shopping, and after Allen shot Brandon she helped him dispose of the weapon.

Allen later pleaded guilty to second-degree murder and agreed to testify against Heather, and Heather was convicted of first-degree murder and conspiracy to commit murder. Did anyone who knew Brandon or his family notice warning signs before August 5, 2013?
