Two parents pleaded guilty Tuesday to leaving their 6-month-old daughter in a car in the Walker Walmart parking lot and admitted to police they were high on OxyContin when they did it.

Billy Arthur Henry Jr., 35, of Denham Springs, and Lana Wallace Henry, 32, of St. Amant, left their child in the locked, unventilated car for nearly an hour on June 27 and told police they did not remember bringing the infant to the store with them, Walker Police said.

The couple told Cpl. Mitchell Fouse they had left three other children with other family members in Walker but “neither subject could tell officers where the family members lived. ... One of the subjects ultimately recalled that the residence ... had a blue door and was near a tire shop on Florida Boulevard,” the release states.

Officers searched the area, found the children and placed them into the custody of the Office of Child Services.

Police found multiple drugs on Lana Henry including synthetic marijuana, Adderall, Opana and Xanax.

Neither posted bond and they remained in jail after their arrests.

Both were charged with child cruelty and unlawful possession of controlled dangerous substances.

Tuesday, 21st Judicial District Court Judge Bruce Bennett sentenced Billy Henry to four years in prison. Lana Henry was given a seven-year suspended sentence.

“Ordinarily, we would have preferred that Ms. Henry serve significant jail time for her violations,” Capt. John Sharp said.

“However, the circumstances of this case are such that the interests of all concerned are best served if Ms. Henry receives the counseling she needs and is able to commence parenting her children as a sober, responsible, dedicated mother who has learned to put the needs of her children ahead of everything else. ... The burden is now on her to do the right thing and comply with the court’s orders. Hopefully, she understands that if she fails, there will be no second chance.”
