A match from a DNA sample left on a piece of latex led police to the 66-year-old suspect who pleaded not guilty this week to killing a 62-year-old man in Koreatown in March, a prosecutor said Tuesday.



Responding to complaints about a foul smell in mid-March, Los Angeles Police found Cornelius Rich dead in his Koreatown apartment at 527 S. Kingsley Drive. He had died about 10 days earlier as a result of blunt-force trauma, police later said.



A small piece of latex, that police believe to be from a glove, was found torn along the zipper of Rich's pants, Los Angeles County Deputy District Atty. John Gilligan said. DNA pulled off the glove eventually matched a sample in the national law enforcement DNA database that belonged to Roy Lee Adams, prosecutors said.
