I-Team: Family identifies girl, 12, allegedly killed by her father

LAS VEGAS - A Las Vegas valley family is making funeral arrangements for a 12-year-old girl this Thanksgiving holiday.

Police say a father killed his daughter and hurt his wife and son before trying to take his own life. 

The I-Team talked with family members and now knows the identity of the 12-year-old girl who police say was killed by her own father.

According to the family, her name is Nevaeh Maddox. Her first name is heaven spelled backwards. The family members are extremely emotional after dealing with death of the girl. The girl's brother and mother were also violently attacked and are in the hospital, along with the suspect.

According to the arrest report for Marcus Maddox, they found the mother Tishia on Sunday night badly beaten with skull fractures and brain trauma. Marcus had shot himself in the head.

The following day, 18 hours later, police discovered the children beaten and stabbed at the Budget Suites south of the Las Vegas Strip.

The 12-year-old girl did not survive.

According to police, she had recently reported to a school counselor allegations against her father of a sexual nature and Child Protective Services and police were involved.

Her mother and 15-year-old brother are in the hospital, along with Marcus Maddox who is technically under arrest and also charged.

The family has set up a GoFundMe page.

Questions have also be raised about why it took police so long to find the children who they say Maddox had left for dead.

The department says it believes there were possible missteps and it's investigating internally.
