In 1998, an economics major threatened to dismember his MATH 111 instructor. Then he went to prison. Then he became a porn actor in California. Then he killed a co-star with a samurai sword. Then, on the run from police last week, he fell off a cliff.

Former university student Stephen Clancy Hill spent hours Saturday on a rock outcropping outside Los Angeles in a standoff with police threatening to kill himself with a sword after spending several days on the run as a murder suspect. He then fell or jumped to his death when police finally tried to capture him, according to the Los Angeles Times.

The pornographic actor performed under the name Steve Driver, and he was almost as disruptive in College Park as he was in Los Angeles. In 1999, Hill was convicted of threatening to chop up a teaching assistant, according to a Washington Post article from the time.

Called “Chilly” by his friends, Hill missed an exam and redefined office hours forever. He asked the teacher, Alvaro Alvarez-Parrilla, for a private meeting, the Washington Post reported. When Hill showed up, he flashed a gun and asked, “What is more important to you … giving me an ‘A’ or your life?”

Hill was arrested several days later after a traffic stop in which campus police found a loaded gun and three fully loaded magazines in his car. At his trial the following March, he testified he did indeed threaten to kill the instructor — but only after the teacher requested oral sex; Alvarez-Parrilla denied doing so. Hill ultimately served about two years in prison.

More recently, on June 1, Hill had fled from police after allegedly stabbing fellow actor and ArmpitGirls.com webmaster Herbert Wong repeatedly with a sword, the Los Angeles Times reported. According to the Internet Adult Film Database, Wong worked on at least six films with Hill, including Cum Fart Tsunami 2, under the stage name Tom Dong.

Articles in the Los Angeles Daily News and the San Francisco Chronicle said Hill apparently killed Wong and slashed two others after finding out that he was going to be fired for “inappropriate conduct” from Ultima DVD — which produces a series of “ballbusters” videos that mostly feature women abusing men — and would therefore have to move out of the company warehouse, where he was living.

When police caught up to him Saturday, he either fell or jumped 40 feet to his death after a SWAT officer tasered him, according to an NBC report.

It’s not just former students who rough up Ultima DVD. According to the Daily Beast, a porn star known as War Machine, a former mixed martial artist, allegedly attacked at least four people at a party in the company offices last year and beat up his agent in a parking lot.
