Denison Police said they are investigating an aggravated assault after a man walking his dog was repeatedly shot by another man wielding a pellet gun.

Lt. Mike Eppler said the incident occurred shortly before 10 p.m. on June 29 in the 800 block of West Monterey Street. Eppler said the victim told officers he was walking his dog down the street when the man with the pellet gun approached him. It was unclear whether the two men knew one another, but Eppler said one witness reported that the dog had previously displayed aggression toward someone in the neighborhood.

“Nobody really seemed to know where he came from, only that he just kind of came from out of nowhere with this pellet pistol,” Eppler said of the assailant. “He told him to get the dog out of there and fired several shots at him.”

Eppler said the victim was treated at an area hospital for minor injuries and released. No arrest had been made as of Tuesday, but Eppler said investigators believe the suspect may be a resident of the neighborhood.

The Denison Police lieutenant said while a pellet gun might not generally be considered a lethal firearm, the suspect could still be charge with aggravated assault with a deadly weapon.

“Anything can be a deadly weapon if it’s used improperly and with the intent to cause harm to someone else,” Eppler said. “It doesn’t matter whether it’s a firearm or not, if it’s used as a deadly weapon, it becomes a deadly weapon.”
