 Only one person was hurt in the shootings that began Saturday along Interstate 10, and that unidentified person suffered a non-life-threatening injury, according to authorities. Two vehicles were struck within a half hour around 11 a.m. Saturday on I-10 between 19th and 59th avenues, and a third vehicle was hit on I-10 near 16th Street about 10:15 p.m. Saturday, according to the DPS. We have some people or person shooting at moving vehicles on I-10," Arizona Department of Public Safety Director Frank Milstead said at a news conference. During a Monday press conference, Milstead said it appears the shooting incidents are random and there is nothing about the targets that appears to be related. "I couldn't tell you what their intent is. A 13-year-old girl suffered a cut to her right ear Saturday morning when a bullet pierced the windshield of the SUV in which she was riding, the DPS said in a press release. The victim stated she heard a loud banging sound however, she did not inspect her vehicle until Sunday 8/30/15; that is when she noticed bullet holes on the passenger side of the vehicle. On August 31, 2015, a fourth shooting occurred eastbound near 24th Street, at approximately 4:25 a.m. A man driving a work truck heard a loud bang and thought that a rock struck the company truck. When he and other passengers arrived at their worksite, an inspection of the company truck revealed the driver side front headlamp had damage consistent with a bullet strike.
– "You should be concerned," a spokesperson for the Arizona Department of Public Safety said during a press conference yesterday. "It has not ended in tragedy, but it could." The AP reports four vehicles have been struck by bullets while traveling along an 8-mile stretch of Interstate 10 in Phoenix, with a 13-year-old girl being the sole injury so far. According to ABC 15, the shootings took place between Saturday morning and yesterday morning, and no suspects or motives have been identified. "We've had bullets hit the sides of the cars; we've had bullets hit windshields," says the DPS spokesperson. Since Saturday, bullets have struck an SUV's window, the headlight of a work truck, and the passenger sides of a tour bus and another vehicle, DPS states in a press release. ABC reports that a 13-year-old girl was cut on the ear when a bullet pierced the SUV, with photos showing a bullet hole in the passenger-side window. At the moment, the shootings appear to be random, and drivers are being warned to stay vigilant. The AP reports police are looking for witnesses and trying to figure out if the same person is responsible for all four shootings.
