ARNOLD, Mo. (KMOX) updated at 1:30 p.m. - A standoff began early Monday morning after police were called to a shooting and found a man with a gun had barricaded himself and two women inside a home. The gunman allowed police to go into the home and rescue one woman who was shot and the other woman was allowed to leave.
After nearly nine hours, the gunman was arrested "peacefully," police say. His name hasn't been released as charges against him are pending, as of Monday afternoon.
The standoff began around 3:20 a.m. in the 3000 block of Adayah Lane in unincorporated Jefferson County, police negotiated the safe exit of a 41-year-old woman who was shot in the chest. She was treated at a hospital for non-life-threatening injuries.
"Police had to go in and pull her out," Jefferson County sheriff's spokesman Grant Bissell said.
Neighbors were never asked to evacuate the area, but were told to stay inside their homes and away from windows.
The other woman, who is the shooting victim's 79-year-old grandmother, got out of the home shortly after officers arrived on the scene and was uninjured.
Police say the suspect was in a previous romantic relationship with the shooting victim and both women lived inside the home.
No other injuries have been reported, but police say at least one gunshot was fired from inside the home since they've been on the scene.
