Sonja Navarro spread mementos of her 13-month-old daughter across her lap and sofa Friday as tears welled up in her eyes: a lock of chestnut hair tied with a yellow bow, a tiny handprint on white paper next to Navarro's own inked palm, pictures of the toddler lying still and quiet.
The keepsakes of Nevaeh Rae Jones, who called every animal "puppy" and danced to rap music, were all made Wednesday, the same day doctors said she was brain dead from apparently being shaken.
Nevaeh's father, Jamie A. Andrews, 25, of Andover, was charged Friday afternoon with two counts of second-degree murder in her death.
Preliminary tests found narcotics in her bloodstream, but authorities need further tests.
"I soaked that little girl with my tears," Navarro said of her last moments with her daughter. "I just wanted her to know I was sorry. I was sorry that I failed her. I was trying to provide a life. I thought I was doing the right thing by leaving her with her dad."
Navarro, 23, of Brooklyn Park, spoke through tears as she recalled how her approximately 90-hour workweek as a nursing assistant forced her to leave Nevaeh with Andrews' mother for days.
She said she dropped the toddler off with the grandmother Sunday afternoon with plans to pick her up Wednesday morning. Andrews lived near his mother and often saw Nevaeh, who was born after the couple ended their seven-year relationship, Navarro said.
Tuesday, Navarro received a "hysterical" phone message from Andrews at 7:42 p.m., saying Nevaeh wasn't breathing.
