Hardin's body was found at 300 Embry on Friday.
Police said he had been shot.
The family said Hardin's car was found burned not far from there at I-45 and Parker on Wednesday.
Police found a body two days after the burned-out vehicle was found. His family was able to identify the body.
The family says Hardin was a loving father of two girls who gave everything to those he loved.
"I still can't believe this is happening. It's just extremely sad for us right now. He was a great dad," said one family member.
His family is asking for prayers.
