The Arizona Department of Public Safety is investigating a pair of incidents that could be part of a string of shootings on Phoenix-area highways over the past two weeks.
On Tuesday, authorities said they were investigating nine cases in which drivers on Phoenix-area highways were targeted. Authorities have said the incidents have occurred along portions of Interstate 10. A reward of $20,000 has been offered and officials say they've received over 100 tips.

Officials aren't sure yet if all of the incidents are connected or if a copycat could be involved.

Arizona Department of Public Safety Director Frank Milstead called the incidents "domestic terrorism crimes."
"Anytime that you have multiple shootings against American citizens on a highway, that's terrorism," Milstead said. "They're trying to frighten or kill somebody."
His agency brought in the FBI, the Bureau of Alcohol, Tobacco and Firearms and local police to help with the investigation.
