On what would have been their 44th wedding anniversary, Yoko Ono tweeted a photo in support of gun control on Wednesday that showed the bloody glasses her husband, John Lennon, was wearing on the day he was murdered, along with the message: "Over 1,057,000 people have been killed by guns in the USA since John Lennon was shot and killed on 8 Dec 1980."

"After 33 years our son Sean and I still miss him."
