Son says he's "blown away" after DNA solves 1988 stabbing death of his mother
CBSN
The San Diego Sheriff's Department said they have solved the 1988 killing of a woman, but the suspect died in an Indiana house fire more than two decades ago. Genealogical DNA testing linked the suspect to Diane Dahn, 29, who was stabbed to death in her Santee apartment, county sheriff's investigators said at a news conference Wednesday .
When she failed to show up for work on May 2, 1988, a colleague from the San Diego Transit Corp. went to her home and found her body in her bedroom. Dahn's son, then 2 years old, was wandering in the apartment complex.
Investigators relied on testing of fingernail scrapings and a hair recovered from Dahn's hands, authorities said.
