Missing baby Lisa Irwin half brother's custody battle hearing delayed until December 7

LIBERTY, Mo. - A hearing regarding a gag order in the custody battle over one of Lisa Irwin’s half-brothers has been delayed until Dec. 7.

Jeremy Irwin, baby Lisa's father, did not appear for the 9 a.m. hearing Tuesday regarding the order in the court battle for custody of his son, Blake.

Earlier this month, Irwin's ex-girlfriend, Rasleen Raim, filed for temporary custody of their 8-year-old son. She said it was for his "safety, comfort and peace of mind."

One-year-old Lisa Irwin disappeared from her Northland home on October 4.

Irwin's attorney said Rasleen hasn't seen her son for six years and that Jeremy plans to fight the petition.
