The latest information:
(1) The surviving housemates and the man loitering near the food truck have been ruled out as suspects at this time.
(2) The two victims at the food truck didn’t walk home. Someone gave them a ride.
(3) The two surviving housemates were not the 911 callers. The 911 caller’s identity has not been released.
From something I read last night; one of the roommates or both became scared when they heard no noise coming from downstairs & one called her boyfriend. He saw someone “passed out” when he looked thru a window & I think he called the police.
This is one of those cases that just gnaw at you because of the sheer horror & mystery involved.
I appreciate your update. Thanks.
