UPDATE: According to posters on the Facebook group, as well as Ballentine's magazine, THE2NDHAND, Ballentine has been found. Tonight's "So You Think You Have Nerves of Steel?" reading has been canceled.

Christian "C.T." Ballentine, a Chicago writer and musician, has been reported missing by friends. The 26-year-old was last seen on Friday, Nov. 6 at 3PM at his apartment in the McKinley Park neighborhood on the city's South Side.

Chicago Police have described Ballentine as white, 6-foot, 135 pounds, with brown eyes and a "badly shaved head," which, according to a Facebrook group set up by his friends, means that "he'll either have patchily shaved hair, no hair or be wearing a hat." According to reports, he was last seen in "a blue jean jacket and blue cut-off shorts with sweatpants underneath." A post on the Chicago Reader says Ballentine's eyes are actually blue and that he has "tattoos of a flower on his left forearm and a man with a cassette deck head on his right bicep." The Sun-Times says friends told police Ballentine was recently "going through some difficult times," but the article doesn't elaborate any further.

Ballentine is known for his involvement in Chicago's music and literary scenes. He's a member of the indie folk band Cup'N'String, provided production work for local band Plan B and works as a sound engineer at venues Ronny's and The Whistler. He's a co-editor of local magazine THE2NDHAND, has profiled bands like Of Montreal and the Stills for UR Chicago Magazine and produced several radio plays.

One of Ballentine's most recent projects is a fundraising reading series called "So You Think You Have Nerves of Steel?" The event is set to kick off tonight at the Whistler at 8PM CT. As of now, it's still scheduled to go on and missing persons flyers can be picked up there.

According to the Chicago Sun-Times, anyone with information should call Wentworth Area detectives at (312) 747-8385.
