Guillermo Contreras of the San Antonio Express-News reports:

Local and federal authorities are searching for former Spurs player Alvin Robertson, who is wanted in connection with a sex trafficking ring that allegedly forced a 14-year-old girl to have sex with men throughout San Antonio and Corpus Christi.

Authorities announced charges against seven people tied to the ring on Friday morning. Of the seven, Robertson is the only one who hasn’t been arrested, said Deputy Ino Badillo, a spokesman for the Bexar County Sheriff’s Office.

“We don’t know where he is,” Badillo said. “We have ICE (Immigration Custom Enforcement) and other agencies looking for him.”
