A Remarkable Outcome in a High-Stakes Criminal Case: Attorney Lindsay J. Killian Secures Probation for Client in a Multimillion-Dollar Theft Case

June 24, 2025

Attorney Lindsay J. Killian of Musi, Mattson, Daubenberger & Clark LLC recently brought a complex, high-stakes criminal matter to a successful conclusion for her client. The case, which spanned more than two years, involved theft in the millions of dollars and was deeply intertwined with issues stemming from illicit drug abuse and the disease of addiction. The client, a mother of two, had struggled with substance abuse that contributed to the circumstances leading to her charges.

Despite the seriousness of the charges, Lindsay saw beyond the allegations. She saw a person struggling…
