An Arizona man who shot and killed the mother of his grandchildren outside a courthouse after a custody hearing in rural Arizona is now charged with first-degree murder.
Navajo County spokesman Adam Wolfe says 47-year-old Salomon Diaz of Snowflake is being held on a $2 million bond.
Police said Diaz had taken care of his son's children for an extended time.
Diaz was charged with second-degree murder at first but now faces two counts of first-degree murder and one count of aggravated assault with a deadly weapon.
His next court appearance is scheduled for July 8.
