A Madison man accused of stabbing his girlfriend Semilla Anderson 29 times pleaded guilty, Friday in court.
Eric Prunn, 40, is being charged with first-degree attempted intentional homicide after being arrested in September at an east side home.
Police said Prunn stabbed his girlfriend inside a home on Brigham Avenue.
Police said they found a woman in her early 30s with multiple stab wounds to her upper body inside the residence. Anderson was Prunn's live-in girlfriend at the time of the attack.
The judge has ordered a pre-sentencing investigation.
A sentencing date has not been set.
