Teen Allegedly Drugged Parents" Milkshakes Over Internet Access A California teenager unhappy with her parents" Internet access rules is accused of drugging milkshakes for her parents in order to put them to sleep, according to police. The parents, who have not been identified, do not allow their daughter to access any wireless Internet at home after 10 p.m. every night. "The daughter didn't think that was a good idea," Rocklin Police Lt. Lon Milka told ABCNews.com. Rocklin is a city about 25 miles northeast of Sacramento. On Dec. 28, the teen and her friend got milkshakes for the parents and "secretly" put the friend's prescription sleeping medicine into the drinks, police said. "They only had about a quarter of the shake because it tasted really funny and had a gritty feel to it," Milka said. But it was enough to affect them and they fell asleep within the hour. The teens were free to use the Internet. The parents woke up around 1 a.m., feeling "hangover-like" symptoms of grogginess and headaches so they went back to sleep. They had not consumed any alcohol or drugs, Milka said. The next morning, they suspected they had been drugged and headed to the police station where they bought $5 drug tests. "Usually, parents buy to see if their kids are using illegal drugs, but these parents used it on themselves," Milka said. The parents said the drug tests were positive and reported the teens to the police. Both teens were arrested on charges of willfully mingling a pharmaceutical into food and conspiracy and were booked into Placer County Juvenile Hall on Dec. 31. The 15-year-old and 16-year-old are not being identified since they are minors.
