HOUSTON -- A judge denied a request to change attorneys for a 10-year-old boy charged with murdering his father, Local 2 reported Tuesday.

The boy is accused of shooting Dr. Rick Lohstroh outside the Katy home of Lohstroh's ex-wife in the 1700 block of Cedar Cove Court on Aug. 27. Lohstroh, a 41-year-old physician, was picking up the boy and his 8-year-old brother as part of a joint custody agreement, officials said.

Lohstroh's parents, Dick and Joanne Greene, were granted temporary custody of the children and filed a motion to have a new attorney assigned.

Dick Greene asked the court to appoint Galveston attorney Anthony Griffin as the new attorney, sources told Local 2 last week.

The boy's current attorney, Chris Tritico, was chosen by his mother.

Tritico was appointed the boy's lawyer before custody of the child was granted to the Greenes.

The Greenes did not want Tritico to represent the boy since he announced that he believed allegations that Lohstroh sexually abused his son. The boys' mother, Deborah Geisler, first raised the claims during the couple's bitter divorce. Two police investigations did not find evidence to substantiate the claims.

A gag order prevents the Greenes from commenting on the proceedings.

In another motion, State District Judge Kent Ellis amended the gag order in the case. The order was challenged by Local 2 News and the Houston Chronicle at an afternoon hearing.

Media lawyers argued motions and court rulings should be made public. The judge agreed.

"The court made some comments that it's important that people know what their elected officials are doing and how matters like this are being handled, and that some amount of information was necessary to be shared with the public," said Joe Larsen, an attorney for the Houston Chronicle.

However, the court hearings will remain closed and none of the parties in the case are allowed to comment to reporters.

The next hearing will be held Nov. 3.

The boy will remain in juvenile detention, where he has been since the shooting.

If convicted, the boy could receive 40 years in prison.
