There was a massive police presence near the area of Baseline and Glenn Way after police received calls of shots fired in the quiet neighborhood.
Sheriff's officials say a 51-year-old woman was shot in the chest at about 6:15 a.m. Tuesday.
Police say that the woman was the suspect's wife. She ran next door to a neighbor after being shot. She was hospitalized and is in stable condition.
The man remained in the home with his mother-in-law.
This led to a hostage situation and a standoff in the Claremont neighborhood. A SWAT team immediately cleared the area and taped off Baseline Road while they tried to get the woman out of the home.
The 90-year-old woman was released unharmed about three hours later.
Residents in the area were not surprised when they heard of trouble coming from the house.
"It is really hard to believe that something like this would happen. No offense, but we kind of called it because there is always something strange going on over at that house. We would drive by a tend to see tons of people outside. You don't usually see that it Claremont. We are a quiet and this doesn't happen usually," said Sabrina Telarroja, a neighbor.
The suspect and victims names have not yet been released. There is still no word of what led to the shooting. An investigation is now underway.
