What drove Sandy Hook shooter Adam Lanza to murder 26 people in cold blood? The answer could lie in his DNA ... and now, geneticists are trying to uncover the microscopic mystery.

The study will take place at the University of Connecticut, where a team of geneticists is reportedly set to examine Lanza's DNA. The team is expected to investigate whether a special mutation is responsible for setting off the troubled 20-year-old on December 14.

UConn's department of genetics is working hand-in-hand with CT's Chief Medical Examiner during the study -- though a rep for the medical examiner's office admits ... they're not really sure what they're looking for.

Results are expected to take several weeks.
