The estranged husband of a missing mother of triplets is "not real forthcoming" in providing information to detectives searching for the Missouri woman who disappeared more than a month ago, police tell FoxNews.com.
Jacque Sue Waller, a 39-year-old mother of young triplets, was reported missing June 1 shortly after visiting with her husband, James "Clay" Waller, at his home in Jackson, Mo.
Waller, who allegedly told police his wife walked away from the home on foot after the two quarreled, has since been named a "person of interest" in the case.
"He's not cooperating the way we hope he would," Jackson Police Chief James Humphreys told FoxNews.com on Tuesday.
Humphreys also said investigators will conduct more searches this week around the area where Jacque Sue Waller's car was found abandoned June 2 along a state highway in Missouri. Police suspect foul play and say it may have been a scene staged to look like an abduction.
The woman, who has 5-year-old triplets, had just attended a June 1 divorce hearing when she drove to her estranged husband's home at around 4:00 p.m. on June 1 to pick up her son, Maddox.
But the child was not at the home when Waller arrived and family members say they believe her husband, a former police officer, lured her to the home to kill her.
Humphreys said Tuesday that police searched the home where Clay Waller was temporarily living within 72 hours of the investigation. He said detectives also uncovered valuable information from the woman's computer that he described only as "personal diary type" in nature.
"We got some information off of her computer that was pretty important to us," he said.
Clay Waller allegedly told investigators that he and his wife had an argument at his home before Jacque "walked away mad," according to Humphreys.
Police found her Honda Pilot abandoned along Interstate 55 in Missouri the morning after she was reported missing. Waller's purse, keys and cellphone were not found inside the vehicle, and Humphreys said there has been no activity on her credit cards and phone since her disappearance.
Last week, a woman reported finding Jacque Waller's Blue Cross Blue Shield business cards along another state highway about 8 miles from where her car was recovered. Waller worked as a manager for the health insurance company.
Humphreys said police will focus searches this week based on new leads that detectives have received. He said investigators have so far generated more than 250 leads in Waller's disappearance, which he said is still considered a "missing persons case."
Anyone with information on Jacque Sue Waller is being urged to call the Jackson Police Department at 573-243-3151.
