California police are investigating the death of a pregnant, 20-year-old mother who was fatally shot in her bed Sunday morning while her 4-month-old son laid next to her, PEOPLE confirms.

Investigators are speaking to several people who were at the party in Amber Baker’s Fresno apartment when the six-weeks-pregnant woman was shot with little Ayden beside her, ABC 30 reports. Ayden was not injured.

“We are sad, mad and confused and out hearts are split wide open,” Baker’s father, Vance Baker, tells PEOPLE. “We can’t even focus on nothing but Amber. And this sad death to my daughter is so unfair.”

He adds: “We want every one to know how great Amber truly was.”
