Calvin Pitts is being held at the Downtown Denver Jail on no bond. He's charged with first degree murder and child abuse resulting in death of his son Sanai Pitts this past summer.
Sanai's mom and Pitts' girlfriend Amanda Deleon is facing the same charges as Pitts.
Pitts spoke exclusively to 9NEWS Crime and Justice reporter Anastasiya Bolton Sunday.
In the interview, the 28-year-old told Bolton the Denver District Attorney and the State of Colorado have it wrong.
"In all honesty, I claim my innocence," Pitts said. "I never really hurt my son."
"Who hurt your son then?" Bolton asked. "I really don't know," he said.
Investigators say Calvin Pitt's and Amanda Deleon's son Sanai had extensive injuries.
The doctors who provided the treatment to the boy said he had two broken legs, a broken left wrist, a burn on the back of his left thigh, a scab on his chin from an unknown injury, an abrasion behind his right ear, and a tear inside his left ear.
Trauma, doctors said, that was not an accident.
"Did you notice any of those in the morning you put your son in the bouncer?" asked Bolton.
"Honestly, it wasn't noticeable to me. If I would've seen it, no matter the consequences, I would've taken him to the hospital," Pitts said.
Pitts told us he suspects Amanda's family members, two people who babysat his son, could be responsible.
"I believe it's because of my past record, it's the easiest way to pin it on. But they don't understand that a parent is not always the one who causes these," Pitts said. "I know the difference between right and wrong. I know some things that I do is wrong, but I would never stoop that low."
The 28-year-old said he loved his son and turned his life around for him.
"I ain't never seen myself living past the age of 30," Pitts said. From all the biz I had out on the streets. Just running the streets. When he came along, he made me change my whole life. I started going back to school and I started doing things that I should've done to change my life."
Pitts said he misses his son every day.
"I sit here and just wonder what life would be like," he said. "It's horrible to sit up here and think about not being able to have my first Christmas with him, or the first New Years with him. Never going to be able to do football. I love him. I love him to death and I would go to the furthest extent for him."
Denver police had this to say about Pitts statements: "Although we can't talk about the details of this case because it's been filed with the District Attorney, there was certainly enough evidence to arrest Mr. Pitts and then the DA felt there was enough evidence to charge him with the crime. However, we're always open to new information and are happy to review anything Mr. Pitts is willing to share with us. It is our desire to get the right person."
Denver District attorney's office couldn't comment on our interview and its content because of Pitts' upcoming trial later this spring.
