The infant's addiction happened because of the mother's irresponsible acts when she used heroin and prescription pain medication, during her pregnancy.
Wilde admitted that he applied crushed Suboxone pills to the infant's gums after the child's birth on April 9th while nurses and medical staffers were out of the room, police said.
Authorities say it's common for parents of drug-addicted children to crush up methadone or Soboxone, drugs used to treat opioid addiction, and rub it into their gums - a method the couple used after apparently learning it from their friends.
Infants born to opioid addicts are usually afflicted by neonatal abstinence syndrome (NAS), which comes with withdrawal symptoms such as tremors, dehydration, hyperactive reflexes, and inability to gain weight.
On June 26, 2017, a few minutes before 3:00 PM, Spanish Fork Police responded to a report of a theft in progress at Walmart in their city.
Panicked Wilde grabbed the vehicle seat and tried to flee through another door. Employees gave him a cash card for the items, not knowing that they were actually stolen.
He was given cash for the items and left the store when employees confronted him about the alleged theft. He responded by running towards the exit while carrying the auto seat with his daughter in it. Wilde attempted to run out of the store while carrying the auto seat.
The auto seat rolled several times when dropped, but Wilde just picked it up and started running towards a different door. Police say Wilde handed his daughter in the vehicle seat to a stranger, jumped into his auto and sped away. He ran with her baby daughter to avoid getting caught, but eventually, he handed the baby to a stranger and drove away in his auto.
Christenson is seen pregnant with one of her older children in 2012.
Authorities said the two younger boys along with the newborn girl tested positive for methamphetamine.
He was arrested on suspicion of DUI and Christenson, who was at the store with her other three sons during the ordeal, was arrested due to an outstanding warrant. The infant was taken to a local hospital to be evaluated according to the statement.
Authorities contacted the eldest boy's father who took custody of the child.
While the parents were in jail, authorities were contacted by a woman asked to care for the pets at Wilde and Christenson's home. They also said they found drug paraphernalia throughout the house, including next to the baby's bassinet and next to a child's sippy cup.
The punishment range for a child endangerment felony charge in most states is two years and could increase up to twenty years.
Family services said the two younger boys and the infant girl all tested positive for methamphetamine. The sheriff's office noted the newborn also tested positive for heroin and morphine.
Christenson was released from jail on June 28, and Wilde was released on July 5 after posting bond. Cannon said when deputies served it on Tuesday, they found Wilde inside his residence smoking heroin.
Following service of the second search warrant on July 18, the couple were arrested again and booked into jail. It's also what tipped them off about the parents' drug crimes.
