An Illinois judge ordered Timothy Bliefnick held without bail Tuesday, a day after Quincy police charged him with the murder of his estranged wife, who was found dead in her home with gunshot wounds last month.

The court also granted the prosecution's request for a DNA swab and scheduled Bliefnick's arraignment for March 24.

Police arrested him Monday morning on charges including murder and home invasion causing injury.

Becky Bliefnick, a nurse who shared three sons with her suspected killer, was found dead on Feb. 23 in her house. The couple was undergoing a divorce and lived in separate houses a mile apart.

His lawyer, Casey Schnack, told Fox News Digital that the boys remained in government custody but were due for a hearing Wednesday to determine whether they could be placed in the care of other relatives.

Prosecutors described the crime Monday as an act of domestic violence, as it happened after Becky Bliefnick sought an order of protection against her estranged husband.

However, Schnack claimed the move was "not uncommon" and accused prosecutors of attempting to craft a narrative.

Tim Bliefnick, 39, has a colorful past – appearing on an episode of "Family Feud" and posting TikTok videos where he posted at least one bizarre joke about Hispanics, preserved by a Twitter user before his account went private.

"Why did the Mexican man take anxiety medication?" he asked. "I'll wait. Think about it. Nothing? To help with Hispanic attacks."

Then he picked up a mug with writing on it reading, "I'm silently correcting your grammar."

Becky Bliefnick, 41, was a devout Catholic who was given an award from the Daisy Foundation for her work as a nurse at the height of the coronavirus pandemic. She was a homegrown hero, having graduated valedictorian from Quincy Notre Dame High School and gone on to Quincy University.
