Days after Illinois police found a nurse and mother of three gunned down in her Quincy home, they served a search warrant at the house of her estranged husband roughly a mile away.

Rebecca "Becky" Bliefnick, 41, was discovered dead with gunshot wounds on Feb. 23, according to the Quincy Police Department.

Investigators on Monday morning were pictured speaking with the husband, Tim Bliefnick, and briefly detaining him before they left. However, police made no arrests and have not accused him of a crime.

"As part of the warrant service, an individual was temporarily detained in the 2000 block of Hampshire and released," police said in a statement Wednesday. "No arrests have been made related to this investigation."

"During a criminal investigation it is not unusual to obtain and serve numerous search warrants for a variety of reasons," police said. "Search warrants are a normal part of the investigative process."

His lawyer said in a statement that she welcomed the search and it would be important to rule her client out so the investigation could focus elsewhere.

"Given the circumstances, it is not surprising that the search warrant was issued and executed," said the lawyer, Casey Schnack. "My only surprise is that it took this long to do."

Schnack told Fox News Digital that police had concluded their search and she was expecting an inventory of items taken.

"Right now, Tim's immediately focus is on the boys," she said.

The estranged couple shared three sons, all of whom have been with their father since last week, she added.
