An Indiana middle school student said his lost phone led to a prank that convinced students and teachers at his school he was dead. Michael Sinkfield, 14, who attends Riverside Junior High in Fishers, said he lost his phone Friday and many of his friends then received text messages from the device Sunday night claiming to be from his father and saying the youth had died in a car crash. The news quickly spread through social media networks, leading to shock when Sinkfield boarded the bus Monday morning and went to school. Sinkfield said whoever had his phone changed his Facebook password, so he was unable to alert friends to the lost device or log in to see the news of his own demise. The family said they do not know who was behind the prank.
