Someone else was supposed to be watching them.
That's the claim made by a 20-year-old Arizona mother charged with the murder of her two young children, who were found dead in a car earlier this week.
The Pinal County Sheriff's Office says there is no evidence that Brittany Velasquez dropped off 2-year-old Christopher or 10-month-old Brooklyn with anyone else.
The sheriff's office, which released a narrative of events in connection to the kids' deaths, says that Vasquez was the last person to see them alive in Superior, a mining town of under 3,000 people.

"There was no proof that Brittany actually dropped the children off," the document said. "It is known that the kids spent several hours in the vehicle as there was condensation on the inside windows of the vehicle and the children were cold to the touch."
The person Velasquez tried to blame denied there was any arrangement for her to take care of them. The other person "stated she had no idea what was happening and did not know what Brittany was talking about," according to the sheriff's document.
Velasquez is being held on $2 million bond on suspicion of two counts of first-degree murder.
Investigators say Velasquez left the children in the vehicle outside a family home at 9:30 a.m. Monday on her way to work. The children were dead when Velasquez returned to the car 14 hours later. They were still in the car seats and wearing the same clothes.

A cause of death has not been determined, but the National Weather Service says the temperature in the region reached 75 degrees on Monday.
"I don't think anyone would imagine this happening to their family," Brittany's sister Amber Velasquez told Azfamily.com. "They were so innocent."
Amber Velasquez said that her sister had taken the kids to the mall for Easter, and the children were pictured with a giant Easter bunny.
"I had nicknames for them. Baby Chris... I would call him 'my papas' and Brooklyn I would call her 'my little fairy,' so I kept thinking not my papas not my little fairy," Amber Velasquez told Azfamily.com.
