Good find.
AH's mother died on June 7, two days before the birth of the new baby. For a normal person, the simultaneous death of one's parent and birth of a child are enough to deal with, especially given the fact that she probably couldn't make the trip to the funeral (or did she even care?). Why complicate your life by committing a murder and/or being an accomplice in a macabre attempt to conceal the crime? Either that woman has ice water running through her veins, or she is on the verge of a complete melt-down.
A few of the most prominent features of her mother's obit are multiple marriages, "splitting" her life between geographical locations, an artsy flair, and overall enigmatic account of her life. Sound familiar? Maybe her mother was a nice woman, but it seems the apple didn't fall far from the tree in some respects.
