PHOENIX - The Arizona Department of Public Safety has identified a person of interest in the case of a dog dragged to its death on Interstate 10 earlier this week.
The person voluntarily came forward, according to DPS officials, and is cooperating with investigators.
The department's investigation is ongoing.
Tuesday, a woman offered a $1,000 reward in the case because she was so horrified about the dog's treatment.
If you have information about this case, you can reach DPS at 602-223-2000.
