Police have offered a £20,000 reward to catch the killer of Diane Sindall, who was raped and murdered by a killer dubbed the "Beast of Birkenhead" in 1986. Nearly 40 years since the murder of the florist, police say new DNA evidence could finally identify her killer. The man police thought was responsible, Peter Sullivan, was released last year having served 38 years in prison - the longest miscarriage of justice the UK has ever seen. #skynews #uknews #uk SUBSCRIBE to our YouTube channel for more videos: http://www.youtube.com/skynews Follow us on Twitter: https://twitter.com/skynews Like us on Facebook: https://www.facebook.com/skynews Follow us on Instagram: https://www.instagram.com/skynews Follow us on TikTok: https://www.tiktok.com/@skynews Sky News Daily podcast is available for free here: https://podfollow.com/skynewsdaily/ For more content go to http://news.sky.com and download our apps: Apple https://itunes.apple.com/gb/app/sky-news/id316391924?mt=8 Android https://play.google.com/store/apps/details?id=com.bskyb.skynews.android&hl=en_GB To enquire about licensing Sky News content, you can find more information here: https://news.sky.com/info/library-sales
