A Maricopa woman found guilty in the 2015 murder of 3-year-old Tiana Rosalie Capps was supposed to face her ultimate sentence today — but that hearing is delayed two weeks.  

Shawn Main, 53, will find out April 25 at 8:30 a.m. if she will be sentenced to life in prison or death after she was found guilty of first-degree murder during a bench trial at the gavel of Pinal County Superior Court Judge Daniel Washburn March 1.  

Main’s wife, Maria C. Tiglao, faces three counts of child abuse and will face a judge May 6 at 1:30 p.m., according to PCAO spokesperson Michael Pelton.  

On Nov. 19, 2015, Pinal County Sheriff’s Office responded to a medical distress call from Main who was driving Capps to a hospital.  

Deputies and paramedics said they met Main near Amarillo Valley Road and Century Road, where she pulled to the side of the road at the dispatcher’s request to start CPR on the child. Deputies found the child and began emergency life-saving measures.  

The child was transported to Banner Casa Grande Medical Center, where she died.   

The toddler lived with her biological mother, Tina Morse, at a home on North Ralston Road in unincorporated Maricopa. Main and Tiglao also lived there. 

The first investigators at the scene reported the house was filthy, with animal feces and belongings stacked throughout the house, typical of a hoarders’ residence.  

They also found Morse’s three sons aged five months, 4 and 5.  

PCSO requested the Arizona Department of Child Safety remove the surviving children from the home. 

Reports showed the 5-year-old boy had injuries to his head and all the other children were malnourished.  

Main, Tiglao and Morse were all arrested on Christmas eve in 2015, 35 days after Capps died. 

Capps was “undernourished,” weighed 24 pounds at the time of her death, and had poor dental health and a severe diaper rash, according to an autopsy report. 

Main was booked on charges of murder and child abuse, while Tiglao and Morse were booked on five counts each of child abuse.  

Despite Main’s claims, the court found last month the injuries were “not at all consistent with a child falling on their own.” 

Pinal County Judge Kevin White accepted a plea bargain in 2016 and sentenced Morse to two years in prison on two counts of child abuse, while three other charges were dismissed, according to court records. Morse was placed on lifetime supervised probation and is not allowed to contact her children.
