A judge is hearing testimony Thursday against an ex-husband whose Bedford County wife has been missing for almost two years.
Shelley Mook disappeared in February 2011 after dropping off her daughter at the home of her ex-husband, Tyler Mook.
In an order of protection obtained by the Channel 4 I-team, the missing woman's mother, Debra Sikora, says Tyler Mook gave her granddaughter matches, and told her to set the home on fire.
Shelley Mook's mother told the court on Thursday that her young granddaughter wrote, "I might kill you," on a dry erase board.
Sikora said she believes Tyler Mook is trying to turn the child against her and says the child brought a pocket knife and matches home after visits with her father.
Tyler Mook's attorney is denying all of those claims.
Investigators have said Tyler Mook is a suspect in his wife's disappearance, but he has never been charged.
Since Shelley Mook vanished, the couple's families have been caught up in a heated custody battle over the child.
