David Vazquez, 32, was booked at the Baldwin Park Police Department on suspicion of murder and was being held in lieu of $1 million.
Vazquez's son, Joshua, was rushed from the family home in the 3700 block of Downing Avenue shortly before 11 a.m. Wednesday to a hospital, where he was pronounced dead.
Police had considered the toddler's death suspicious. The cause of death has yet to be determined.
