Verna McClain is accused of gunning down Kala Golden Schuchardt outside a pediatrician's office, then abducting her 3-day-old son back in April. Investigators believe McClain wanted to pass the baby off as her own.
The DA's office says it's going through all the evidence that's been gathered in this case and is almost ready to take it to the grand jury.
"At this point, we're convinced that she acted alone, that no other participants helped her out," said Assistant District Attorney Warren Diepraam.
The DA's office plans to decide on the death penalty issue in the next couple of weeks. They have 90 days to get the case to grand jury for consideration of an indictment.
