The Forest Hills mom found dead in a hockey duffel bag Saturday was seen alive in her yard a day earlier — hours before video caught a mysterious figure apparently lugging her makeshift casket down the street.

Orsolya Gaal, 51 — whose body was discovered by a dog-walker around 8 a.m. Saturday — was remembered by her shocked Queens neighbors over the weekend as a typical stay-at-home mom who was married and had two teen boys.

“I saw her [Friday] in her backyard,” next-door neighbor John Bankson told The Post.

“We share a common backyard with [her] dog,” the resident said, apparently referring to an adorable little brown pooch that Gaal posed with in a slew of Facebook photos on her page.

“[Saturday] morning, we were like, ‘Why can’t we hear the dog this morning?’ It’s super shocking,” Bankson said.

The NYPD said Sunday that surveillance footage from the area captured “an unknown individual” dragging a wheeled duffel bag from the direction of the stately Tudor-style home where Gaal and her family lived.

The hockey bag containing her corpse was found nearby, and cops followed the trail of blood from it back to the side door of her Juno Street home, authorities said.

Officers found Gaal’s 13-year-old son on the top floor of the home, police said.

“He stated he lives at the location but does not know where she is,” cops said in a statement.

The boy was taken into custody to be interviewed and later released, law-enforcement sources said.

Gaal’s husband, businessman Howard Klein, was reportedly in Portland with the couple’s 17-year-old son on a college hunt at the time, according to social-media posts.

Klein told The Post on Saturday that he was on his way home while repeatedly saying the family’s lives “are at stake.

“There are concerns about our safety, he said. “Our lives are at risk.”

In a since-deleted tweet announcing his recent out-of-state trip with his son, Klein also made a pitch for hedge-funder Bill Browder’s book about Vladimir Putin.

“Just landed Portland OR before evaluating Ann Arbor again with my 17-year-old son,” Klein wrote. “Highly recommend ‘Freezing Order’ @Billbrowder a man I’ve followed closely and admired since I started on Wall Street in 1997 broking EMEA & Russian equities to hedge funds like Hermitage.”

The book is subtitled “A True Story of Money Laundering, Murder and Surviving Vladimir Putin’s Wrath.”

According to sources, Gaal was previously reported missing in May 2020 but later surfaced.

The couple’s older son also went missing in 2004 but was later found, too.
