That is a trick the media plays, when I studied Journalism (it was my minor) we called it Yellow Journalism. A news agency using spectacular headlines to grab ones attention. William Randolph Hearst was notorious for this kind of trick. Many historians feel that Hearst was responsible for the Spanish American War due to his massive power in the newspaper industry and his brand of yellow journalism.
The police did not say he is guilty and he committed the crime, they can't. It is up to the District Attorney to file charges, the Grand Jury reviews the case, the suspect is arraigned, and the suspect has a trial. Only then can guilt be set by a jury of the suspects peers. In this case the news station is using the Police: blah, blah blah trick. I believe it is because it is a TV station and an online story they can get away with it. If the print media posted a headline like this there would be hell to pay in the editorial office.
P.S. William Randolph Hearst was the chief influence for the character Charles Foster Kane according to Orson Welles. He hated Hearst and his politics. It is rumored but has never been proven that Rosebud was Hearst's nickname for Marion Davies (his mistress) private parts.
