DMX must have had some sort of episode behind bars because he was just moved to the mental health unit in the Alhambra lock-up in Phoenix, AZ.
From the Phoenix New Times
Rapper Earl Simmons, better known as DMX, is housed in a mental-health unit at an Arizona State Prison Complex facility called Alhambra near 25th street and Van Buren.
DMX's manager, Nakia Walker, wouldn't comment specifically on whether DMX might have a mental disorder, but she says she wasn't surprised when he was moved to a mental-health unit. The rapper himself always has refused to comment on speculation about his mental state. In 2001, he threatened to beat up writer William Shaw for asking about it in a Blender magazine interview. "Waaaay too personal," DMX said.
Arizona Department of Corrections files confirm that DMX was admitted to the Flamenco Mental Health Unit at Alhambra on December 20. According to Walker, he will not be allowed to have visitors for 30 days.
