Deleon's aunt is coming to her defense, saying she'd never intentionally hurt anyone.
Lisa McIntosh says she spent years living with Deleon, and says her niece was almost like a second mother to her own two young children. When she got the news Deleon might have harmed her own, first-born child, McIntosh says she simply couldn't believe it.
"There's not a good explanation for anybody to hurt an infant," McIntosh said. "There is no excuse for it. When this came out, we were all just flabbergasted about it."
McIntosh says she has known Deleon since she was very young.
"She is a loving person and she loves kids," McIntosh said. "She's been taking care of kids since she was a kid, and she has never hurt anybody in her life."
McIntosh describes Deleon as an intelligent person who had fallen on hard times over the past few years, living on the streets of Denver and having some problems with the law. She says recently, Deleon had been trying to turn her life around.
"She is a one-of-a-kind person," McIntosh said. "She is very smart. She graduated from culinary school and she's trying to get ahead."
McIntosh says Deleon started dating Calvin Pitts about nine months ago, and says ever since then the couple's relationship with the rest of the family has been strained.
"At times he wouldn't let my sister-in-law hold the baby," McIntosh said. "He would be possessive and wouldn't let her hold him and that's her grandson ... why wouldn't she let her hold her own grandson?"
As to why Pitts might have acted that way, McIntosh says she can only guess. She says she never got to know him that well.
"I just say don't ever point fingers because you never really know anybody's situation," McIntosh said.
One thing she does know is that her nephew is gone, and she says her family won't rest until they know how and why.
"The baby was hurt and we're going to get to the bottom of it," McIntosh said.
McIntosh says her niece checked on the baby early in the morning on the day he died and said the infant appeared to be okay. McIntosh says it was an hour or so later when Pitts discovered the baby wasn't breathing, and that's when she said Deleon called 911.
Pitts and Deleon are being held in the Denver County Jail. At this point, nobody has been charged for the death of the child.
