Arizona authorities questioned a "person of interest" in the shooting on Friday, and he was booked on unrelated charges. Arizona DPS representatives said that their investigations of the highway shootings are not closed. There is also talk of a possibility of more than one shooter because of different MOs used. Drivers are afraid to use the interstate due to the shootings and Arizona authorities are stepping up their efforts to solve the case as soon as possible.
In a news conference on Tuesday, DPS officer Frank Milstead called the shootings "domestic terrorism."
"Anytime you have multiple shootings against American citizens on a highway, that's terrorism"Milstead also said that it was fortunate that no one has been killed or seriously hurt, but if the shootings continue, "it's just a matter of time before there is a tragedy." Investigators do not know what the motive is for the shootings as of yet. As mentioned before, they also are not sure if the shootings are connected or if they are just "copy cat" shootings and more than one shooter is involved.
A press release on the Arizona DPS website details each attack, which seem to be random. A message from local crimestopper hotline Silent Witness was also posted asking for information about the shooter or shooters.
"Silent Witness is offering $20,000 for information that leads to the arrest of those responsible for these shooting incidents. The number for Silent Witness is (480) WITNESS - 480-948-6377."An LED board also asks for drivers to call in with any tips involving the Arizona highway shootings.
