Bad Henry (9 p.m., Investigation Discovery) -- The ID channel premieres a two-hour special about Charlotte serial killer Henry Louis Wallace, also known as The Taco Bell Strangler. Wallace was a fast food manager who murdered 10 women in Charlotte (and one in Barnwell, SC) before being caught. Most of his victims had connections to the Taco Bell where Wallace worked or to a local Bojangles restaurant, where Wallace’s girlfriend worked. Much of the special is told from the perspective of retired homicide detective Garry McFadden (of the ID show “I Am Homicide”), who took over the case as the murder victims started stacking up and outrage in Charlotte increased.

Frontline: UN Sex Abuse Scandal (10 p.m., PBS / UNC-TV) -- This Frontline special traces allegations of sex abuse by United Nations peacekeepers in conflict zones around the world, featuring firsthand accounts from survivors, witnesses and officials.
