The murder trial of Darnell Griffin abruptly concluded this afternoon, without the defendant taking the stand to explain how his DNA was recovered from the body of victim Evelyn Luka.

Griffin, 50, is accused of raping and murdering Luka, 19, in September 1999. He wasn't charged in the case until a DNA sample taken from him in 2006 was matched the following year with sperm recovered from Luka's body as she lay in a coma after the 1999 attack.

Defense lawyer E. Edward Aquino said in his opening statement that the jury would hear during the course of the trial that Griffin and Luka had consensual sex two days before she was attacked.

But no such evidence or testimony was introduced at the trial, as Griffin decided not to testify in his own defense.

Closing arguments will be delivered tomorrow morning.
