Final answer:
The notorious killer known for escaping from prison and being dubbed the Chi Omega Killer after a series of murders is Ted Bundy. He was infamous for his crimes throughout the 1970s and methodically lured his victims before committing egregious acts.
Step-by-step explanation:
The infamous killer referred to in the question is Ted Bundy. Known for his escape from prison twice and for the series of heinous crimes he committed across the United States, Bundy was finally captured and convicted. In Utah, he was convicted of kidnapping an 18-year-old, which was just one crime in his long list of offenses. Bundy's notorious reputation was further cemented after his second prison escape, when he was dubbed the Chi Omega Killer following the brutal murders at the Chi Omega sorority house at Florida State University. The term deliberate stranger refers to the methodical and impersonal way he approached his victims, often luring them with charm and faked injuries before committing his crimes.
