CRYSTAL LAKE, Ill. (WLS) -- The foster family of Andrew "AJ" Freund, the young Crystal Lake boy who was found dead last Wednesday, has released a statement Tuesday remembering the "happy, fun-loving" 5-year-old.
The statement reveals that the foster family had been prevented from having contact with AJ. The statement was issued by the foster family and one of AJ's biological grandmothers, an attorney said.
The statement read:
"We, the family that lovingly cared for Andrew (AJ) during the first 18 months of his life and were then allowed to be in his life for another 26 months until the parents abruptly prevented us from having any further contact with him, want everyone to know that AJ was loved by us with all our hearts.
While we had him in our lives, he had a happy, fun-loving life. This smart little boy loved having books read to him, doing puzzles, his Thomas the Train, playing with his fire trucks, bulldozers, cement mixer and Ninja Turtles. He was very curious and always wanted to learn about everything.
He was, and will always be, our loving and caring little boy. With his brave short life, AJ made the ultimate sacrifice to save his younger brother and unborn sibling. His life shall not be in vain. AJ will always be our little superhero.
We want to thank the Crystal Lake Police and surrounding Police Departments, the FBI, all other first responders, and our community at large. We appreciate all of the kindness, prayers, love, and compassion shown by all."
Both of AJ's parents have been arrested in connection to his death according to police.

The McHenry County Coroner's report shows AJ died of multiple blunt force injures to the head.
Investigators said the boy was forced into a cold shower for an extended period of time and badly beaten before he died. His parents then allegedly wrapped their 5-year-old son's body in plastic and dumped him in a shallow grave in the woods.
