EL MONTE — An infant hospitalized in critical condition after he stopped breathing Wednesday, leading authorities to a marijuana growing operation allegedly run by the child’s parents, has died, officials said Friday.

Three-month-old Caidan Phu died about 3:40 p.m. Thursday at Children’s Hospital of Los Angeles, according to El Monte police and Los Angeles County coroner’s officials.

He was rushed to the hospital about 10 a.m. Wednesday after his mother awoke and found him not breathing and called 9-1-1, El Monte police Lt. Dan Burlingham said.

While tending to the baby’s needs, police noticed an indoor pot growing operation of about 100 marijuana plants growing in a room of the house, Burlingham said.

The baby’s parents, Van Phu, 30, and Jing Jao, 21, were arrested on suspicion of cultivating marijuana and child abuse, Burlingham said.

As the investigation continued, he added, police were less convinced abuse was involved in the child’s death, Burlingham said. There were no signs of physical trauma on the infant, who apparently suffered from medical conditions.

The investigation into the child’s death hinged on the findings of coroner’s medical examiners, who will perform an autopsy do determine exactly how the baby died, officials said.

Both suspects were released from jail on $100,000 each pending their initial court appearance in El Monte Superior Court Feb. 23.
