Ex-DePaul tennis player, Northwestern coach charged with stalking

Tribune reporter

An Australian tennis coach with ties to Northwestern and DePaul universities stalked his ex-girlfriend in Chicago, threatened her life and said he'd post nude pictures of her online, prosecutors alleged Saturday.

Mark Terry Henderson, 32, is accused of attacking the 29-year-old on May 7 after months of bothering her online. Henderson had been in an on-again, off-again relationship with the Chicago woman for more than five years before she broke up with him in February, prosecutors said.

Henderson, who played tennis at DePaul and coached the sport at Northwestern, now lives in Australia but flew back to the U.S. a day before the alleged attack, Assistant State's Attorney Alexandra Molesky said. He is charged with aggravated stalking, officials said.

For months, Molesky said, Henderson had bothered his ex-girlfriend through phone calls, emails and texts. At one point, the prosecutor said, he sent the woman a collage of naked photos and threatened to post it online if she didn't send him more nudes.

Molesky said Henderson threatened the woman's life and continued doing so even after being contacted by Chicago police and Australian authorities.

On May 7, Molesky said Lake Forest police found Henderson sitting outside the woman's parent's house. Later that day, prosecutors said Henderson approached the woman on Sheffield Avenue, confronted her and again threatened her life.

Henderson grabbed at the woman, who ran toward her car and locked the doors, Molesky said. Henderson then went around and tried all the car's door handles, prosecutors said, but the woman was able to escape and call 911.

Henderson then fled to Tennessee, police said, where he was arrested on a $500,000 warrant signed by a Cook County judge on May 9. He was extradited to Chicago and taken into custody by officers here on Thursday afternoon at O'Hare International Airport.

Prosecutors asked Judge Maria Kuriakos Ciesil to hold Henderson without bail, but she instead ordered the $500,000 bond amount to stand. If Henderson bonds out, the judge ordered that he surrender his passport, refrain from using social media, undergo GPS monitoring and not leave Cook County.

Henderson is a DePaul graduate who played for the Blue Demons for two years, where he earned third-team all-conference honors, according to a news release on the Western Michigan University web site, where he later served as an assistant coach.

Henderson also worked as a volunteer assistant coach with the Northwestern women’s team during the 2009 season, according to the WMU news release announcing his hiring.

Before becoming a coach, Western Michigan said Henderson was the top-ranked Australian man and on one of the world's top-60 doubles teams.

Henderson, whose current address is in Queensland, Australia, told the judge Saturday that he wanted his country's consulate notified of his arrest. He'll be back in court Tuesday. | Twitter: @MitchKSmith
