UPDATE: Las Vegas police have named Marcus Maddox as the suspect in the stabbing of two children at the Budget Suites on South Las Vegas Boulevard and the attack of the woman on East Craig Road.
ORIGINAL STORY: One child is dead and another is in critical condition at UMC Trauma after being stabbed by a man believed to have been their father.
Police say they received a call at about 6 p.m. Sunday about a man attacking his wife at Siegel Suites in the 5200 block of East Craig Road.
The man and woman were transported to UMC Trauma. The woman is in very critical condition and the man is in critical condition.
The children were discovered on Monday morning by an employee of Child Protective Services at the Budget Budget Suites near Las Vegas Boulevard and Wigwam. It is believed that the father harmed the children on Sunday before hurting himself and their mother.
The children are believed to be 12 and 15 years old. Police say that the 12-year-old girl who died was stabbed in the chest. The 15-year-old boy was also stabbed and has a skull fracture.
Police say that CPS knew the children's whereabouts and went to check on them after hearing about the incident involving the parents.
A police spokesperson say that their officers became aware that the man had been accused of sexually abuse involving a child while investigating the incident between the man and the woman but they did not know where they could be found on Sunday night.
The police department says that they will be looking into why the information about their location was not communicated to them and hope that the mother is able to speak at some point. They don't know at this point how the woman was separated from the children.
The Clark County coroner will release name of deceased. This is a developing story. Check back for updates.
