Inquiry hears parents tracked Barnaby Webber's phone to police station

David Webber tried to contact his son after hearing about the attacks, but got no response. As he and wife Emma tracked the phone's location and called police, he was told no one could speak to him, increasing his sense of fear. Barnaby was one of three people killed in Nottingham by 34-year-old paranoid schizophrenic Valdo Calocane.
