Police in the Twin Cities arrested a man in his 30s Sunday morning on suspicion of murder after officers found his dying roommate.

The Richfield Police Department says shortly after 5 a.m., officers were called to the 6400 block of Bloomington Avenue South on a report that a woman had cracked her head open in the shower.

Upon arrival, officers found a 37-year-old woman on the floor in the basement's bathroom with a large laceration on the top of her head. Despite lifesaving efforts, she died from her injuries, police say.

Officers reported seeing signs of struggle in the basement living area, as well as signs that there had been an attempt to clean up blood. Court documents state the woman's 2-year-old daughter was found asleep in their bedroom with blood spatter on her.

The Richfield Police Department says the woman's roommate, a 37-year-old man, was covered in blood and had fresh injuries to his hands. 

Police arrested the man, saying his description of events appeared to be inconsistent with the crime scene evidence. He was charged on Wednesday with one count of second-degree murder, according to court documents.

The incident remains under investigation.
