A neighbor ran after the attacker and slowed him down just long enough for police officers to catch up with the suspect and arrest him.

“We just heard screaming. We got worried after hearing one really loud scream. We walked over there and saw a lady laying on the floor,” Shanes Edeleeuw recalled.
