GREELEY, Colo. -- One of three dogs that attacked a Weld County woman last September bit another woman this month, shortly after the dogs' owner finished serving a jail sentence for the first attack.

Three Attacks, One Dog

The latest incident occurred a little more than a week after David Riley's release from jail, authorities said.

According to the Weld County Sheriff's Office, Pamela Flanders was bitten on the neck while she was visiting Riley's mother on May 9. Jackie Riley was issued a citation for owning a dangerous dog as a result of the latest incident. She had been keeping the dog for her son, David Riley.

The dog was one of three boxers that were seized from David Riley earlier after one bit Rosa Storm on her hand on Sept. 3 while she was walking her Siberian huskies in Firestone, Colo., according to investigators.

The three boxer-mixes were also blamed for an attack on Adam Stutzman, 18, at the Coal Ridge Animal Hospital in Longmont, where the dogs were impounded while Riley awaited trial in Storm’s case. Stutzman spent four days in intensive care recovering from several severe wounds sustained in the attack. His injuries required more than 200 stitches to repair.

Prosecutors said they couldn't bring charges in the attack on Stutzman because of a technicality in Colorado law. The law doesn’t allow criminal charges to be filed against the owner of a dog that attacks a handler who is caring for the animal.

Meanwhile, Riley was sentenced to 60 days in jail in March for the attack on Storm. After his release on May 1, he was required to keep his dogs in a razor-fenced kennel, or muzzled and leashed when they were outside the kennel.

Upon his release, Riley told the Longmont Daily Times-Call that his dogs would no longer bite people because they were trained at the Colorado Dog Academy in Broomfield while he was in jail.

"They've spent a couple months at the Colorado Dog Academy," he told the newspaper. "They really trained them good."

The woman who said she was bitten in the latest attack has her own pet trouble with authorities. Police removed 26 sick cats from her Dacono home on Feb. 25. Seventeen of the cats were euthanized because authorities aid they were too sick to recover or too wild to be adopted. The surviving cats were given to the Longmont Humane Society.
