A Colorado man charged with killing his pregnant wife and two young daughters in the midst of an affair with a co-worker once gave a presentation on relationships and infidelity, specifically mentioning the idea of infidelity with a person at work. "Sometimes you find your partner no longer attractive physically or in their personality," Christopher Watts says in a 9-minute YouTube video posted in April 2012, six months before his marriage to Shanann Watts. "Even at the job, you might meet a new person and [the new relationship] could strengthen into something else," he continues, delivering a presentation titled "Communication Speech, Relationship Deterioration and Repair," which he says is for a course he was taking. At one point, Watts notes children "could help repair" a deteriorating relationship, as could listening and showing affection.
"Great job Christopher! Good information!" Watts' future wife commented on the video, viewed more than 100,000 times, per CBS News. Along with recent vacation photos, other videos of the couple are racking up online views. "He's the best thing that has ever happened to me," Shanann says of her husband in one, per the Coloradan. Another viewed nearly 12 million times shows Shanann surprising Watts with news of her third pregnancy. "That's awesome," Watts says before kissing his wife. Authorities allege he killed her and daughters Bella, 4, and Celeste, 3, weeks later. Watts has a different version of events, claiming he killed his wife only after she strangled their daughters following a conversation about a possible separation, according to police. He's next due in court in November. (Read more Christopher Watts stories.)
