Police say they responded to the home in the 400 block of Doyle Avenue shortly after 5:30 a.m. after receiving a suspicious circumstances call. They found the 46-year-old mother dead. Police are not commenting on the cause of death.
Police also found the woman's 21-year-old daughter injured. The daughter was treated at the scene and taken to the hospital, where she underwent surgery. Her condition is unknown, police said.
Police located the woman's son, 25-year-old Pablo Hernandez Jr., outside the home. He was arrested and charged with murder and attempted murder.
People who know the suspect say the crime is hard to believe.
"I couldn't really tell you much about him, I didn't know him that much. He wasn't that kind of guy to go and do something like that to his own family," said Manuel Padilla.
