Shot: Sandra Kay Sutton, below, and her 17-year-old son Zachary Wade Sutton, above, have been found shot dead at a relative's home around three weeks after she escaped her ex-boyfriend's home.
Sutton and her 17-year-old son, Zachary Wade Sutton, were found dead on Thursday at a relative's home in Clinton, about 45 miles from Sedalia, where she had moved after escaping the home she had shared with Horn.
Oberkrom said officers found Horn hiding in a closet in an abandoned building at the J. N. Turkey Kearn Memorial Wildlife Area, about 70 miles southeast of Kansas City. He said officers were led to the area by a tip they received Saturday morning.

When officers told him to surrender, Horn threatened the officers with a handgun, said Sgt. Bill Lowe, spokesman for the Missouri State Highway Patrol. Lowe said it was unclear if Horn fired his weapon.

A massive hunt is underway for a man suspected of shooting dead his ex-girlfriend and her teenage son just weeks after she told police he had kept her locked in a wooden box for months.
Sandra Kay Sutton, 46, and her son, Zachary Wade Sutton, were found dead in her brother's home in Clinton, Missouri, where they had been staying, around 4am on Thursday, police said.
Authorities said her former boyfriend, 47-year-old James Barton Horn Jr., is 'absolutely' a suspect in the murders and officers surrounded his home in nearby Sedalia early on Thursday.
They have been looking for Horn ever since Sutton escaped his home in April and accused him of keeping her captive inside a wooden box for months.

Wanted: Police say that her ex-boyfriend, James Horn, is 'absolutely' a suspect in the deaths.
In late April, Sutton told police that, in January, Horn threatened her in a car with a 'tire jack' after an argument and that when they returned home he began building a wooden structure.
She said that Horn forced her to help build it, according to a probable cause statement filed by Sedalia police in the case.
The probable cause statement also said Sutton was allowed to leave the box in the evenings when Barton returned home from work but remained locked in it throughout the day.
When he returned, he sexually abused her, she said.
She managed to escape and run to a neighbor's home on April 30.
