GREELEY, Colo. (CBS4)– Police in Greeley want to talk to anyone who had contact with a 4-month-old infant before he died. Investigators believe Donovan Nathan Archuleta was abused because of injuries found when he was rushed to the hospital.

“I’ve been just thinking of that little boy. I just close my eyes and I just see his face,” said Denise Velasquez, grandmother of one of Chavez’s other children.

Responding officers and paramedics noted that there were visible injuries on the child and investigators suspect child abuse in his death.

“There were injuries on the child necessitating the investigation,” said Greeley Police Sgt. Joe Tymkowych.

Stunned family members gathered at the Greeley courthouse on Tuesday.

“It’s sad, you know. Nobody knows anything yet so, it’s like a puzzle to all of us,” said relative Debra Gonzales.

They say the baby’s mother is Angelica Chavez and his father is Robert Nathan Archuleta. Chavez’s four other children are from different fathers and some of their families are fighting to keep Chavez away from the children.

“I just want justice for the baby. The baby needs a voice; he needs somebody to stand up for him. He’s no longer with us and we’ve got to do everything in our power to make sure the right thing happens to the right person,” said Velasquez.

Donovan’s mother hid her face as she left the court hearing.

Four other children in the family were placed into protective custody. Tymkowych said officers collected evidence from the apartment after obtaining a search warrant.

Tymkowych said there are no suspects but there are several persons of interest including Donovan’s mother.

“Anyone who has had any contact with the child recently would definitely be a person of interest,” said Tymkowych. “We would look at them as a possibility for some of the injuries that occurred.”
