In Lincoln, Nebraska, a 43-year-old woman was discovered dead in her apartment on Thursday morning, following concerns from her family who had been unable to reach her for several days.

Family members, equipped with a key, allowed police to enter the apartment where they found Tracy Henman deceased from a neck injury, as reported by the Lincoln Journal Star.

Inside the apartment, a 40-year-old man was also present and was taken into police custody without resistance. He was subsequently hospitalized due to injuries on his face, neck, and arms, though the authorities have not elaborated on the nature of his or Henman’s injuries.

The police stated the man’s injuries were not life-threatening, but he remained hospitalized on Friday. His identity will not be disclosed until he is discharged and officially charged.

No other individuals were present in the apartment at the time. Authorities confirmed that the man and Henman were acquainted, although they have not specified the nature of their relationship.

It’s also not known how long she had been dead when police arrived at the apartment. Family members said it had a been a few days since they’d been able to reach her, Assistant Police Chief Jason Stille said.

Stille said investigators are working on a “number of different elements of this case, including interviewing people who know the victim and the suspect and reviewing evidence,” KOLD reported.

He said that charges against the suspect are awaiting results of an autopsy.

Capt. Ben Miller said Henman had children who also lived at the apartment occasionally, but they were apparently not there on Thursday morning when police arrived, according to the Journal-Star.

“Anytime somebody is found deceased, we would look at murder and the murder charges, but some of that needs to be determined based on the autopsy and then having conversations with the county attorney’s office and marrying that up with the other evidence that we have,” Miller said.

Henman worked for the Hy-Vee grocery store company, where co-workers said she was a beloved employee.

“She was just always so happy and bubbly,” said Blayre Raddock, who worked at a different location but was friends with Henman. “She’d see me walk into the door, she’d get a giant smile and she’d come give me a hug.”

“She had such a big heart and always was happy to see her friends,” Raddock said. “And I know her kids were her everything.”
