This incident was puzzling to investigators.
Crime's like this in this neighborhood, let alone Kingsburg, are rare.
It happened at about 8:00 p.m on Seventh Avenue, just west of Highway 99.
It was originally reported that 51-year-old Robert Ellis heard a noise in another part of the house, and went to check on it.
Kathryn Ellis reported that she hid in the bathroom during that time.
She said she heard several gunshots.
Chris Curtice, Fresno Sheriff's Office: "When she went to check, she found her husband in the living room. He'd been shot, at least one time, and he was deceased at the scene."
After speaking with deputies further, Kathryn Ellis was arrested, and charged with murder.
Neighbors say they often saw Bob Ellis and his son playing catch in their front yard.
Some came out of their homes during the overnight investigation, saying crimes like this are rare, not just in their neighborhood, but in all of Kingsburg.
Jennifer Allen, Kingsburg Resident: "Everything usually locked up tight, but now I'm not quite sure whether or not to go out, because I feel safe at home, but yet it's really quiet here during the day, so that's very unnerving."
The day after, the neighborhood is even more quiet.
Jennifer Allen has lived here for over eight years.
Some have lived here for 30.
When residents heard it was an intruder that may have done this, they were in shock.
But now that Robert Ellis' wife has been arrested for the murder, it's even more so.
Allen: "Him and the child played ball, but it wasn't anything out of the ordinary. Just families, they ride bikes here, they play catch, they just hang out."
Detectives say a weapon was recovered, and Kingsburg police say there was no history of domestic violence at the home.
Kathryn Ellis was arrested at a relative's home in Clovis, and is facing one count of murder.
Deputies say there are no other suspects.
Deputies say her son was present at the time of the arrest and has been turned over to Child Protective Services.
