"Eroshevich was with Smith through her pregnancy in the Bahamas, the birth of her daughter and death of her son Daniel."
If that is true, and KE was there all that time, how very, very strange that KE would leave one day before she died.
Then he waited a little while for Daniel's flight to come in and took Daniel to the hospital, leaving the drugs in the car.
After taking the photos of a Happy Daniel, Anna and Baby, HOWARD got hungry and asked if anyone else wanted anything. He didn't exactly bring back a gourmet meal. Hospitals have vending machines all over the place and it was late at night. There was really no reason for him to go out except to get to his car.
When he came back, he brought the lethal drugs with him.
Most hospitals now have video cameras in their parking lots and there is likely a video at the food place. I think they may be useful to LE. Howard's very controlled in his actions. The tapes might show otherwise.
I wonder if KE and HKS have a "thing" going. They have known each other for years and maybe KE wanted ANS gone - NOW. Maybe she jumped the gun before HKS told her to.
