Devitt was walking home earlier this month when a pack of pit bulls attacked her and bit her to death. Authorities said that Devitt received 150 to 200 puncture wounds from the fatal mauling.
On the same day of the attack, authorities investigated Jackson's home, where detectives said four of his eight dogs seemed to have blood on their fur and muzzles.
After DNA tests matched Devitt's blood to the blood on the dogs' fur, police charged Jackson with murder.
Devitt's husband, Benjamin, told NBC Los Angeles that he didn't blame the dogs. He blamed the owner.
"You get caught up in somebody else's irresponsibility and these kinds of tragic, devastating things happen," Devitt said.
Jackson faces life in prison if convicted. According to NBC Los Angeles, local officials said they couldn't remember a similar murder charge involving a dog attack in the last 10 years.
