A bomb squad was dispatched to the home of a missing Missouri mom during a search after a hand grenade was found.

The hollowed-out grenade was found Friday in a gun safe in the house Renee Pernice shared with her husband, Army Sgt. Shon Pernice, according to MyFOXKC.com. It turned out to be disarmed. The safe belongs to Shon Pernice.

Neighbors were asked to stay inside until the Kansas City Police Bomb Squad was finished investigating, MyFOXKC.com reported.

Investigators planned to continue their search of the home on Saturday, according to the Kansas City Star.

Renee Pernice was last seen Jan. 2 by her husband, who says she left home about 9 a.m. that morning but he doesn't remember where she told him she was going. Her cell phone was found in a park about 12 to 15 miles from her home.

The search warrant was executed Friday at the house in Northland, Mo. Authorities said it could last for 24 to 36 hours.

The disappearance of the mother of three has been called suspicious. Police say they suspect foul play. No arrests have been made.

Shon Pernice has only spoken to detectives through his attorney. He recently returned from service in Iraq and has said he has been suffering from stress. The couple had been having marital problems.

Anyone with any information about the missing woman is asked to call the TIPS Hotline at (816) 474-TIPS.
