re: silence from LE, family
I've been thinking about this as well. There are some obvious similarities between this case and
Kiely Rodney's: both involve young adults heading home after a night out partying with friends -- friends who let them go their separate way despite their intoxication, rather than sticking together to ensure that they made it home safely.
Considering how absolutely horrid the public was to Kiely's family and friends, I could definitely see LE encouraging BB's family and friends to keep a low profile to avoid having this turn into a media circus -- especially if they have solid reason to believe that BB fell into one of the ponds and are just waiting for his body to resurface.
