22-Year-Old Stabs Two Friends, Builds A Too-Perfect Alibi

On the night of March 21, 2025, someone broke into a house on West Healy Street in Champaign, Illinois, and attacked the two people inside with a knife. Twenty-two-year-old Nathan Goodman was killed. His girlfriend, twenty-two-year-old Caitlin Lassie, was stabbed in the neck, spine, and stomach—a single millimeter from her carotid artery. She survived. That detail is the one Alex Muanambuta, a 23-year-old with no criminal record, never planned for.

By the time detectives read him his Miranda rights, Alex has a story ready. He was home with his girlfriend, then at the mosque, then back home, then back to the mosque for his forgotten wallet. The alibi comes out smooth and complete—almost too rehearsed to be real. What Alex doesn't realize is that his own story is already competing against things he can't talk his way around: GPS data placing his phone on that street that night, and blood already sitting on his shoes and in his car door, waiting on lab results.

The Interrogation Opens

The interview begins not with an accusation but with a careful legal distinction. Detectives tell Alex he is detained, not arrested—a status that requires a Miranda warning but does not yet mean formal charges. "You can't just walk out of here," one detective says, "so that's why we read the Miranda warning, because then you know that you're not free to leave at this time."
