It appeared that they were hit by a vehicle, Aurora police spokeswoman Cassidee Carlson said.
"They were spotted on the side of E-470 at East 64th Avenue by a state trooper," Carlson said.
That location is about 11.5 miles north of where the attacks occurred -- in 19200 block of East Gunnison Circle, near South Dunkirk Street and East Jewell Avenue in the Louisiana Purchase subdivision.
"Aurora Animal Care Officers took possession of the dogs. Aurora Animal Care Division will continue to investigate in an attempt to identify the owners of the dogs," Carlson said.
Three people were injured in Friday's morning attack, which started when a woman was walking her small dog on a path.
Two of the victims were treated and released. The condition of the most seriously injured woman -- the walker -- remains unknown.
Cheryl Schultz told 7NEWS she was preparing to go to work around 6:30 a.m. when she heard a woman screaming and the dogs barking and she ran out to help. Schultz said she saw the woman trying to protect her small dog from two pit bulls so she ran out to help.
After yelling to try and stop the attack, Schultz said she tried to pull one pit bull away. That's when both dogs -- a black pit bull and a brindle-colored pit bull-- lunged at her, she said.
Schultz tried to run back home but was knocked to the ground. With the dogs distracted, the first woman and her small dog jumped into the back seat of a car whose driver stopped to help, Carlson said.
Schultz's husband ran outside and helped her scurry back to their apartment. Shultz said she was inside her apartment, calling 911 when she looked out her window and saw a third person -- later identified as Brad Wall -- being attacked by the two pit bulls.
Wall said the attack happened quickly and as he was defending his neighbor's life, the dogs turned on him. He said they knocked him to the ground.
"They were mostly going for my throat. That’s why I had to block them up high and when I did that the other one worked on my legs," he said. The dogs bit his legs, tearing at his skin, jeans and arms, he said.
"I was able to kick them enough to where there was a car parked here and as they went around to regroup to attack me again, I got up and jumped on top of the car," he told 7NEWS.
The dogs circled the car and then ran north shortly before officers’ arrived at the scene.
Both women were transported to the hospital. Wall has had a tetanus shot, antibiotics and may have to undergo treatment for rabies. Schultz was released with several stitches to her leg.
Schultz said she's never seen those pit bulls in the neighborhood and neither of them were leashed. She said the brindle-colored dog -- the one with black and brown markings -- was wearing a blue plaid neckerchief.
