Police in Hudson, Wisconsin, say they made a shocking discovery following an hourslong standoff overnight Thursday.

Officers responded to a welfare check along Namekagon Street just after 3 p.m. on Wednesday. Police say a man called them and made comments that led them to believe someone was in danger inside the home.

Investigators say he was also threatening to force officers to fatally shoot him. In the end, he was taken to St. Croix County Jail.

While searching the home afterwards, police say they found the body of a 54-year-old woman who lived at the residence. They're still investigating the cause of her death.

Police arrested Chad Haworth, 54, after an hours-long standoff. St. Croix County court documents charge Haworth with first-degree intentional homicide after a woman was found dead in his home. Haworth cut the woman's neck, documents said.

Hudson police said Haworth made comments which led them to believe someone was in danger inside.   

Court documents said Haworth "…had concerns that his wife was cheating on him, possibly poisoning him with their cats medicine…" Haworth told law enforcement, "She's no longer with us, she's deceased," documents said.

Jaidyn Anderson lives right next door to Haworth's home.

"I was really nervous," Anderson said. "I felt that something bad maybe happened, because I could hear like banging and screaming."

A few doors down, Tina Parker said she counted 100 police and sheriff's deputies, some in her backyard and on her deck, armed with rifles, while they ordered her to stay inside.

"A tactical unit came in. They were speaking to the man demanding he come out," said Parker.

Some of the windows on Haworth's home are smashed. Neighbors said law enforcement either fired non-lethal rounds or teargas inside.

After several hours, Parker watched and recorded on her phone as Haworth was taken into custody.

"It was a harrowing experience, something that I've never been through, and hopefully never will be again," said Parker.
