An Arizona mother has been arrested after her two young children were found dead strapped to their auto seats in her vehicle.
A 2-year-old boy and a 10-month-old girl were found dead in a vehicle at a home in the town.
Foul play is suspected and their mother, Brittany Velasquez, was arrested on suspicion of two counts of murder, Forghani said.
Authorities have not released the children's cause of death, or identified the victims.
Superior is a rural community located roughly 60 miles east of Phoenix. She was jailed and authorities did not know whether she had a lawyer who could comment on the allegations, said sheriff's spokeswoman Navideh Forghani.
Superior Interim Police Chief Christian Ensley said in a news conference Tuesday that the mother had first called authorities about the incident.

An investigation is still underway by the sheriff's office.
"This is a devastating blow", Ensley said.
Ensley said the children's father had died a year ago and he personally knew many members of the Velasquez family in the small, tight-knit community.
Pinal County Superior Court Administrator Todd Zweig said Velasquez would be represented by the county public defender's office, where officials said a specific attorney had not yet been assigned to her case. "There were no legal grounds to remove the children from the parent's custody".
Relatives told Fox10 thet believed the young mother was mentally unstable and that they've called Department of Child Safety several times out of concern for the children.
Both children were found strapped in their vehicle seats when officials arrived. The nearby mine is closed now but a mining company is trying to reopen it.
