GREELEY, Colo. (CBSNewYork/AP) — A man who strangled his pregnant wife and suffocated their two young daughters wanted to escape his marriage and growing family, prosecutors said Monday as a judge imposed a sentence of life without parole after a plea deal kept the killer from facing the death penalty.

Christopher Watts, who pleaded guilty two weeks ago, did not speak during the hearing. One of his attorneys said Watts was “sincerely sorry.”
