The investigation is active and anyone with information is encouraged to contact
Detective Rubio at (925) 372-3454 or at erubio@cityofmartinez.org.
Stating suspect was located in the area and detained by officers tells me that this was not likely self defense. A mother’s duty is to love their child unconditionally.
Must take legal or other steps to distance from the angst. I’m sure Investigators will do their due dilligenge. Tragic.
Bella.
The mother has a history of mental health issues, schizophrenia to be exact per people that know the family well
Dang this is tragic.
