A sicko senior allegedly tried to buy a baby girl from her mother at a Louisiana auction house, according to police.

Howell Gene Penton, 73, allegedly asked the mom to sell him her 10-month-old daughter late last month while they were at the Angie Auction House in Angie, about 120 miles east of Baton Rouge, according to the Washington Parish Sheriff’s Office. 

He was busted Saturday after an undercover operation by the sheriff’s office and local cops.

The balding senior was charged with attempting to buy a minor child and is being held at the county jail on a $200,000 bond, jail records show.

No other details have been released on exactly how he asked the mom or if he knew her.
