Father, children found dead after 24-hour standoff in Missouri

A 24-hour standoff at a Missouri apartment complex ended on Monday evening, when police broke into the home and found the dead bodies of a man and two of his children, officials said.
The Springfield Police Department said in a statement that officers breached the apartment door and found 51-year-old William Williams, who appeared to have died from a self-inflicted gunshot wound, and the bodies of his daughter and son, aged 2 and 4 years old.
It was not clear from the statement how the children died. A police spokeswoman could not be immediately reached to provide details.
The standoff started after police received a call to make a check at the apartment complex around 9:30 p.m. local time on Sunday and they encountered the armed suspect. Police conducted negotiations until breaking into the apartment on Monday, police said.
