Brooklyn teen Tyree Wright was charged with first degree assault and acting in a manner injurious to a child in the death of his girlfriend’s 23-month old son Jacquil ¬†Degraffenreid. Tyree Wright was baby-sitting the todler while the mother went to work.

Tyree Wright has a criminal record, with five arrests for crimes involving trespassing, assault and robbery. Jacquil Degraffenreid died from blunt impact injuries that caused lacerations to his liver, and pancreas that led to internal bleeding, the NY Daily News reports.

How many more children will die at the hands of mothers’ boyfriends before people wake up and exercise some caution about the people they arllow around their kids? Clearly this woman was trying to do the right thing by working but she left her child in the care of a thug.
