A pair of Texas teenagers are facing aggravated assault charges after hitting an elderly woman and a young boy with blowgun darts in the parking lot of a Houston-area Wal-Mart, authorities said. Harris County authorities reviewed surveillance footage from the Jan. 16 incident in Tomball, and were able to track down the suspects, reported NBC affiliate KPRC. Cameron James Perry, 18, who police say blew the darts from the backseat of a white Nissan, was arrested Tuesday and jailed on a $30,000 bond, according to the Harris County Sheriff's Office. The driver, Clay Vittrup, 18, was also apprehended and posted the same bond amount.

The teens are accused of hitting a 10-year-old boy on his right arm as he walked into the store with his mother, KPRC reported. They then allegedly struck Eva Cook, 72, who was riding a motorized scooter. She told the station that she was caught off guard by the dart hitting her. "I turned around and saw this thing out of my shoulder," Cook said. "I shop there all the time, and was just minding my own business and was just in shock," she added. Both teens are due back in court over the next month.
