On June 28, two days after the parents were arrested, a woman who took care of the couple's pet, called the authorities when she found drug- paraphernalia at the their house.
The couple first came to the attention of the authorities last month, when Mr Wilde was arrested on suspicion of drug possession, driving while intoxicated and driving without insurance, among other possible charges.
After their release, authorities received a tip suggesting the couple were back on drugs.
As witnesses tried to stop him, Wilde handed the auto seat and his baby to a stranger, then ran to his vehicle and sped away, according to deputies. Christensen was in the store with her other three young children during the incident and was arrested on an outstanding warrant.
"Bedrooms, family rooms, bathrooms, there was a substantial quantity of drug paraphernalia in those areas, all areas where those children would have immediate access to those items", Cannon said.
It was during this investigation process that authorities learned about Christenson's heavy drug use during pregnancy and the subsequant damage done to her newborn baby. She told police she arrived to find drug paraphernalia in the home.
Besides the newborn, Christenson's other three children, ages 8, 4 and 2, lived in the house with the couple, the Sheriff's Office said.
BBC gender pay gap revealed: two-thirds of top earners are men
A legal expert has predicted that the BBC could be hit with a wave of equal pay claims from female stars. Match of the Day's Gary Lineker is the second highest earner, making £1.75-1.79m.
Using the description from Walmart loss prevention employees a Deputy with the Utah County Sheriffs Office, who was near the area, found the suspect driving away from the area and stopped him in the parking lot. Christenson and her 29-year-old boyfriend also admitted to crushing pills of Suboxone, a prescription painkiller and applying it to the infant's gums just hours after she was born. DCFS became involved in the case, having all four children tested for drugs. They were placed in the custody of the oldest boy's father. The infant girl was checked into a local hospital. If there is a known history of drug use by a mother, then her baby will be evaluated and if necessary, receive treatment for withdrawal symptoms.
They are now being held in a county jail on a $10,000 cash bail. Also lying around was Suboxone, some of it in pill form, the rest of it crushed. This resulted in her daughter being born already addicted to drugs.
Because the four children lived in the home and could have been in risky proximity to the paraphernalia and prescription pills, the police added four counts each for Wilde and Christenson for child endangerment, which is a third-degree offence.
Because they knew their daughter would be born an addict, Christenson and Wilde later told investigators "they talked to friends about how to mask signs of drug dependence in an infant, and that they discussed this issue with each other", the sheriff's office claimed in a statement. Three of the couple's youngest children tested positive for meth. They also caught Christenson in the act of smoking heroin. The parents tested positive for opioids and methamphetamines, and police charged them with new counts, including distribution of a controlled substance in a drug-free zone, endangerment of a child, possession and use of heroin and methamphetamine, and possession of drug paraphernalia.
Bail for Wilde and Christenson is now set at US$10,000.
Christenson was released from jail on June 28, and Wilde was released on July 5 after posting bond.
