Richard Ramirez: The Night Stalker Tapes

9pm, Sky Crime

Between April 1984 and August 1985, Richard Ramirez murdered at least 15 people in California. He died in 2013 while awaiting execution on San Quentin’s death row. In this two-parter, interviews with Ramirez’s wife (Doreen Lioy), friends, female admirers and family members, along with those with his victims’ family members, are aired for the first time. It also examines 80s fan culture, and why he was celebrated by some like a rock star. Hollie Richardson

Eight years after his 2006 film The Wind That Shakes the Barley delved into the 1920s Irish war of independence and civil war, Ken Loach returned to the country to assess its uneasy peace circa 1932. In an absorbing, fact-based story, communist Jimmy (Barry Ward) returns from the US to his County Leitrim home to reopen a community hall, which exposes the continuing rift between the working class and “the masters and the pastors” who dictate their lives and block democratic change.
