Investigators determined that the stabbing happened in a third-floor apartment, police said.
A witness told police that Waite and Locke came to the apartment to visit. The couple got into an argument.
According to a criminal complaint, the witness “knew from her observations that Locke had stabbed him” and asked “Sandy, what did you do?”
Locke ran, but was later taken into custody with the assistance of McKeesport police.
