Summary

At 9:27 PM on February 1, 2021, Matthew Farwell entered Sandra Birchmore’s apartment building. At 9:56 PM, he left. Twenty-nine minutes. Sandra was never seen alive again. When her body was found three days later, she was wearing the same clothes. Federal prosecutors allege that inside those twenty-nine minutes, Farwell strangled Sandra and her unborn son, then staged the scene.

The forensic evidence prosecutors have assembled is devastating. Farwell’s DNA was found on the duffel bag strap used to strangle Sandra. His sperm cells were found in her underwear, contradicting his claim that he hadn’t been intimate with her in months. Sandra’s right clavicle showed an injury that occurred while she was alive, matching the buckle behind her head — evidence prosecutors say proves she could not have died in the position she was found. A broken pink flamingo necklace Sandra regularly wore was discovered tangled with her hair on the bedroom floor. Her phone recorded its final movements while Farwell was still inside the apartment.

Then there’s the reenactment. At a private gathering after Sandra’s death, an inebriated Farwell demonstrated how she supposedly died, positioning himself beneath a doorknob. The details he described had not been publicly revealed. He knew because, prosecutors allege, he staged the scene himself.

DNA testing later confirmed Farwell was not the biological father of Sandra’s unborn son. But both he and Sandra believed he was — and prosecutors say that belief is what drove him to kill her. Every piece of physical evidence points to homicide. And yet, for years, it was ruled something else entirely.

This is Part 3 of a five-part series on the Sandra Birchmore case.
