CEDAR FALLS -- A man with a permit to carry a firearm detained a Cedar Falls man when he started stabbing people at his apartment building last month, according to authorities.
According to police, Adam Scott Jacobsen had stabbed fellow tenant Jeffrey Miller 24 times and apartment manager Denice Bennett eight times at University Avenue Studios apartments before Daniel Williams drew his firearm.
“He pulled the gun and ordered him to lie on the ground,” said Chief Jeff Olson with the Cedar Falls Police Department. He said Jacobsen complied and remained there until police arrived.
“Before police got there, he holstered his gun,” Olson said.
Olson said he didn’t know if Jacobsen would have continued his attack without Williams’s intervention.
Moments before the Oct. 17 attack, Bennett and Williams, who Olson said was Bennett’s boyfriend, were both headed to the building in separate vehicles. Williams was caught at a red light, so she arrived first. He pulled in about a minute or two after Bennett was stabbed.
Charged with two counts of attempted murder, Jacobsen was moved to Unity Point Health-Allen Hospital for a medical and psychiatric treatment on Oct. 20 after he began showing signs of psychiatric stress.
Court records show that after the Oct. 17 stabbing, Jacobsen talked to investigators about requests from God. He said demons were everywhere killing people and had him cornered, and God wanted him to kill the demons, court records state. He told police he killed a demon and accidentally killed a "good person."
