Detective Karnes, a senior investigator, just arrived at a crime scene. Officer Miller, who is running the case, tells him the facts they know so far:

The crime scene is an apartment. Inside is the lifeless body of Regina.
Investigators know it is Regina because her husband, Solly, the landlady Margie, and neighbor Les have all identified her.
Earlier, people in apartment 1B heard lots of yelling, thumping, and a scream, so they called 911.
Solly also called 911. He cried into the phone as he told the dispatcher, “Please hurry, I think my wife is dead!”
Paramedics arrived first and pronounced Regina dead at the scene.
They did not determine a cause of death.
They did note that Regina had a number of bruises, some that were old, and some that might be fresh.
She had cuts over her body, but none that seemed large enough to account for the amount of blood on the scene without some other explanation (such as thinned blood).
The most notable injury on her body is an indentation from a blunt object on her right temple.
Paramedics noted that Solly was hysterical.
The paramedics treated him for shock, but he would not leave Regina's side.
When Officer Miller arrived, Solly was still next to Regina on the floor, covered in blood. Solly told Miller, “I killed her! I did it!” Miller asked Solly what he meant, but Solly became hysterical again and nothing else he said made any sense or even sounded like real words, just sobbing. Paramedics told Officer Miller they needed to take Solly to the hospital, and if the officer intended to arrest Solly, he needed to accompany them. So Officer Miller went with Solly.

At the hospital, before hospital staff sedated Solly to calm him down, he grabbed Miller's hand and told him: “I shoved Regina. We had a fight, and she was drinking. We were both mad, and I pushed her. She fell and hit her head on the kitchen table. And she never got up! I did it. I never should have laid a hand on her, and I'm sorry. I want to do the right thing here.” Officer Miller returned to the scene and noticed that the corner of the kitchen table had blood and hair on it. He wrote a note to the medical examiner, asking for a test of Regina's blood alcohol level.

Officer Miller returned while Detective Karnes was collecting evidence. Officer Miller said, “There's really not much you need to do here. We got a full confession.”
