Few answers Tuesday in gun range shootings ***UPDATE***

AURORA |  Circumstances surrounding a double shooting Monday at the Cherry Creek State Park shooting range remained murky Tuesday, investigators said. 

Arapahoe County sheriff’s office Capt. Louie Perea said investigators are hoping to interview the surviving victim of the shooting but have not been able to because she remains hospitalized in critical condition. 

The woman, who is the twin sister of the 29-year-old woman killed in the shooting, underwent surgery yesterday for a gunshot wound to the head, Perea said. 

Until investigators can talk to her, they likely won’t know what happened inside the shooting stall at the Family Shooting Center in the park near Parker Road and Interstate 225, he said. 

“Everything is still on the table,” he said. 

The two women, who were from Australia, were inside a stall when the shootings happened, he said. 

Perea said investigators aren’t sure who fired the gun or guns, or whether the same bullet hit both sisters, who were in the same shooting lane. The sisters had taken a taxi to the range and had been there for more than an hour when they were shot.

Surveillance video shows that the two women were the only people involved in the shooting, but because the camera didn’t look directly into the stall, Perea said it isn’t clear exactly what happened. 

He said it isn’t even clear yet if a crime occurred or if the shooting was accidental. 

The surviving woman could shed some light on what happened, Perea said, but investigators aren’t sure yet when or if she will recover to the point that investigators can interview her. 

“It all depends on how quickly she improves,” he said. 

Investigators will not release the names of either woman until next of kin has been notified, he said.
