Murder suspect's mom charged in deaths of 2 witnesses

Prosecutors have charged a St. Louis woman with arranging the deaths of two 16-year-old boys who were potential witnesses in a murder case against her teenage son — a case that initially fell apart because other witnesses then refused to testify.

Latashia Mopkins faces two counts each of first-degree murder and murder conspiracy, among other charges made public Wednesday. Her brother, nephew and a third man also face murder charges in the deaths of one or both of the two teenage witnesses, and prosecutors reinstated the original murder charge against her son, Tyrell Davidson.

All five are jailed without bond.

Investigators allege that Davidson fatally shot 16-year-old Chauncey Brown in September 2013. Two other 16-year-olds who were witnesses were later killed. Mopkins is accused of offering money for the killings.
