'Shark Tank' Star Offers to Replace Boy's Stolen Prosthetic Leg, Will Send Family to Disney Land

Robert Herjavec was so touched by the story of 4-year-old Liam Brenes that he offered to replace the boy's stolen leg.

One of the stars of the entrepreneur competition series Shark Tank was has offered to buy a California boy a new prosthetic leg after his old one was stolen during his first trip to the beach. 

Robert Herjavec was so touched by the story of 4-year-old Orange County boy Liam Brenes that he offered to replace the prosthesis that was swiped by heartless thieves on Sunday morning.

And while the TV star and businessman was beaten to the punch after throngs of supporters offered to help the family, Liam's mother told InsideEdition.com that Herjavec insisted on giving them something nonetheless.

"He sounds like an amazing person and he still just wanted to do something," Amanda McFarland said.

Herjavec has pulled some strings at Disney and, at some point after he's fitted with a new prosthesis, Liam, his parents and brothers will be treated to a VIP tour of Disney Land. 

His mother said Liam couldn't be more thrilled.

"He's very excited, he's bugging me to go for a long time now," McFarland said. 

After her son's story went viral, McFarland said a number of prosthetic makers lined up to help the family. "It's a strange position to be in to have to choose," she joked.

Eventually the family settled on California company Essential Orthotics and Prosthetics, who've managed to rush the order. Just a few days after his leg was swiped, Liam will get a new prosthetic.

A GoFundMe that the family started before they knew they'd be gifted the prosthetic will now go toward expenses for Liam and toward sending him to a camp with other children facing the same challenges. The rest will be donated to Shriner's Hospital in Los Angeles, McFarland said.

The heartless thief struck Sunday at Crystal Cove State Beach in Orange County. Leaving the leg and other items such as a camera and Liam's glasses on top of their cooler in the sand, the family hit the water.

But when they returned, the personal items — including the leg — had been stolen.

His father, Frank Brenes, wrote on Facebook, "My four year old son is now without his leg because of these people... I am crushed."

Liam's mother Amanda McFarland told InsideEdition.com she felt angry and helpless when she heard what happened at the beach.

"I was very mad but I was mostly just worried about him," she said. "I didn't know how he was going to feel and how it was going to affect him."

According to Brenes, Liam was diagnosed with FATCO syndrome, a rare condition that caused him to be born with only two fingers on his left hand, and no right fibula bone.

At just 1 year old, the boy had his leg amputated above the ankle at Shriners Hospital for Children in Los Angeles. To help him get around, he wears Star Wars- or pirate-themed prosthetics.

But since his custom leg was stolen, his mom said they are still working out the logistics of replacing it.

McFarland explained the most basic functional prosthetic can cost upwards of $10,000.

"Little guy has such a better attitude about it than me," Brenes wrote. "He's just like, 'I'll ask Santa to put something important on my list.'"
