A Dallas woman faces up to 20 years in federal prison for her role in the overdose death of an apparent first-time heroin user.
Cierra Allyn Rounds pleaded guilty Tuesday to conspiracy to possess with intent to distribute a controlled substance. Rounds remains jailed pending sentencing.
Prosecutors say 19-year-old Rian Lashley of Dallas died last March after using heroin she allegedly bought from another suspect.
Authorities say Rounds and two other suspects determined Lashley had $3,000 and had never tried heroin. Investigators believe the teen was targeted for the cash when she accompanied the suspects to Rounds' home.
Prosecutors say Rounds and another suspect, at Lashley's request, injected heroin into the teen. Lashley died hours later.
One co-defendant awaits trial on conspiracy, possession and distribution-related counts. Another remains at large.
