This week Reasonable Doubt looks at the the murder of Sarah Gonstead and the conviction of her friend Penny Brummer.
Madison, Wisconsin on March 14, 1994, and 21-year-old Sarah Gonstead went out for some drinks with Penny Brummer and never returned.
It would be nearly a month before a cyclist discovered her body in some woods, she’d been shot in the back of the head.
The police investigation soon focussed on Gonstead’s drinking buddy that night, 24-year-old Penny Brummer. She was the last person who admitted seeing Gonstead before she died and they also thought that she had a motive.
Brummer was dating one of Gonstead’s best friends and was said to get really jealous when they spent time with each other. She also had access to her dad’s gun of the same caliber that was used to kill Gonstead and that gun was missing.
Witnesses placed the two together at a bar near where the body was found and some of them seemed to contradict Brummer’s recollection of the night.

However, Brummer protested her innocence and her supporters say that the veteran may well have blacked out several times that night after the binge drinking. They also say she had an alibi in the form of an unlisted TV show she remembers watching whilst the murder took place and that there is no evidence tying her to the crime either.
She remains in prison.
Reasonable Doubt airs at 10:00 PM on Investigation Discovery.
