ORIGINAL STORY

A mother was fatally shot at the 4600 block of Dealers Choice Way, near Boulder Highway and Tropicana Avenue.

"I'm speechless cause it literally happened right next to me," says Josh Reffner, who lives next to the woman who was killed.

Two children under the age of ten were inside the home. One of them found their mother dead inside her bedroom with a gunshot wound and called 911 around 8:55 a.m. Saturday.

Police are searching for a man presumed to be the father of the children. He is considered a suspect in this case.

Reffner says he's seen the father at the home before.

"I didn't think he was that type of person he seemed pretty cool like I'd be out there everyday and he'd be out there playing with his kids," says Reffner.

Officers have also contacted Child Protective Services, and are looking for family members related to the children.
