Mayra Perez's relatives learned Thursday what they had already feared: The northeast Denver woman shot her three children and then herself. What they might never know is why.
Denver police confirmed that Perez, 23, killed two of her children, critically wounded a third and then killed herself. Two-year-old Isabel Perez remains in a deep coma.
"What's done is done," said Perez's brother, Tony Nuñez. "Whatever reason drove her to this, it's going to be in God's hands. He'll be the judge of her. We have to focus our prayers and hopes on my little niece."
Nuñez spoke at a news conference at Denver Health Medical Center, where Isabel is being treated.
"We're working with our doctors to keep her supported at this point," said Dr. Claudia Kunrath of the hospital's Pediatric Intensive Care Unit.
Isabel's father, Ricky Perez, spent Tuesday night at a friend's place after arguing with his wife.
Police said he returned home just before 7 a.m. Wed-nesday to find her body and those of her daughter, Nevaeh Morales, 4; and son Erick Perez, 1. Nevaeh suffered multiple gunshot wounds, while her mother and brother each died of a single gunshot, the Denver Medical Examiner's Office said.
Paramedics rushed Isabel from the family's home in the 4900 block of North Pearl Street. Ricky Perez told The Denver Post he had been by his daughter's bedside but was too distraught to comment further.
"He's the one who made the call to us," said Denver police major-crimes Cmdr. Ronald Saunier. "He's been very cooperative throughout this."
The commander offered few new glimpses into the attack Thursday, declining to discuss what evidence and any weapons detectives recovered.
Nor would Saunier say whether investigators had determined a motive for the killings, which stunned the woman's relatives and left neighbors to wonder about the seemingly happy family that walked their dog and rode their bikes around the block. A ribbon of yellow tape that blocked their access Wednesday was gone, allowing passers-by to peer into a yard strewn with children's toys.
Mayra Perez's relatives in Cunatillo, Texas, have said the couple sometimes quarreled, but they saw nothing in their recent interactions with her that gave them pause.
"I want to ask for a prayer to guide us through the hard times we're going through," Ricky Perez's cousin, Edgar Munoz, said at the news conference. Neither he nor Nuñez took reporters' questions.
