The other 3-year-old child sickened in an overdose in Canoga Park last week has died, police said.
The twin boys of 22-year-old Jestice James were in cardiac arrest when first responders found them late Thursday morning in the 20100 block of Sherman Way, police said, and one of the twins, Josiah James, died at the hospital later that day.
The other boy, whose name has not been released, was initially in critical condition but died on Saturday, according to Los Angeles Police Department spokesperson Norman Eisenman.
Police have thus far only identified the suspected narcotic that caused the overdose as an “unknown substance.”
Jestice James was booked into the Valley Jail in Van Nuys on suspicion of murder after the first child’s death and her bail was set at $2 million.
Jail records indicate James is due to appear in court on Monday.
