- The victim was in stable condition at a Seattle-area hospital
- Police say the suspect was intoxicated
The victim was in stable condition after she was shot in the torso Thursday night in Renton.
She was in the theater watching the movie "13 Hours: The Secret Soldiers of Benghazi" when the shooting occurred, CNN affiliate KOMO reported.
The unidentified suspect took off after the shooting, the Renton Police Department said in a statement.
His father later called 911 and said his distraught son told him the gun discharged after he dropped it in the theater, authorities said.
But police painted a different picture.
"We have witnesses that say he came into the theater and appeared intoxicated. He went in and took a seat in theater No. 9 and was fumbling with a pistol when it went off and struck someone sitting in front of him," David Leibman with the Renton Police Department told the affiliate.
After the father's call, police went to the home and arrested the suspect without incident.
Renton is about 10 miles south of Seattle.
