Body found in Boston's Charles River on New Year's eve is missing college student Dennis Njoroge (shown in the poster below).

A native of Kenya, Njoroge moved with his parents to Massachusetts in his youth. They filed his missing persons report when he uncharacteristically lost touch with them and failed to attend anymore school activities.
A month later, on December 31st, a young man's corpse was spotted in the Charles River, and positively identified as the missing college student over the weekend.
This is the same waterway where the body of 23-year-old grad student Jonathan Dailey was discovered in the winter of 2012, bound in chains and weighted with cement.
It's also not far from the city reservoir where missing honors student Franco Garcia was found drowned, after he mysteriously vanished while using a downtown ATM.
As with Dailey's and Garcia's peculiar cold-weather drownings, Boston police are claiming there is "nothing suspicious" about the similar disappearance and death of Dennis Njoroge as well.
In fact, they informed reporters yesterday that they don't even plan to fully investigate it because -- as is typical for waterlogged bodies -- there were "no signs of trauma" on Boston's latest drowned young man.
