KANSAS CITY, Mo. — The mother of slain pregnant woman whose body was found on Christmas Day says she began to worry as her grandchildren opened gifts because she couldn't reach their mother in Kansas.

Prosecutors alleged this week that 31-year-old Jenna Schafer was fatally shot as part of a contract killing. Two suspects have been arrested .

Tonya Cullen is raising her 10- and 11-year-old granddaughters and says Schafer had planned to watch the girls open their gifts through Facebook Messenger.

The family made several frantic calls before learning Schafer had been found dead in a trailer in Junction City.

Mashaun Baker and Dion Green are charged with capital murder in the case. Prosecutors haven't said how the men may have known Schafer or what prompted the killing.

Cullen says Schafer was "trying to clean herself up and make things better for her girls."
