Yang is accused of killing Rhoni Reuter in 2007.
Yang's lawyers asked Lake County Associate Judge Christopher Stride to suppress court-authorized body wire taps that Yang's friend, Christi Paschen, obtained during a conversation. They also want the judge to get rid of two taps authorities retrieved from Yang's cell phone.
Stride has approved the use of the phone wire taps but has not ruled on the use of the body taps.
During a January 2008 police interview, Yang did not confess to the murder, but she referenced a 9 mm gun stolen from her home. That gun was used in the shooting. During the interview, Yang confessed she was jealous of Gayle's other girlfriends.
Associate Judge Christopher Stride is scheduled to rule on the latest wire taps Feb. 18.
Yang is being held in the Lake County Jail.
