DNA sketch leads to suspect confession in Texas slaying

DALLAS (AP) A private lab used DNA to make a facial sketch that helped lead police in Texas to a suspect in a woman's May 2016 slaying.

Brown County sheriff's investigators announced in mid-November that they had charged 21-year-old Ryan Riggs with capital murder in the beating death of 25-year-old Chantay Blankinship.

Riggs confessed a week after the department released a suspect sketch made by analyzing DNA from the crime scene.

Law enforcement officials say the technology can help narrow their suspect pool or generate new leads in cold cases.

But some ethicists and lawyers have raised concerns that not enough is known about the link between genes and facial features and putting out a suspect sketch without any witnesses could lead to racial profiling or other ethical problems.
