Feb. 14 (Bloomberg) -- New York City detectives went to Pennsylvania today to question a 43-year-old man who is a ``prime suspect'' in the slashing death of an Upper East Side psychologist, WCBS-TV reported, citing unidentified people.

The Pennsylvania resident became friends with the victim, Kathryn Faughey, after they met at a guitar camp six years ago, WCBS said, citing the unidentified people. He wasn't a patient, the pair weren't romantically connected and the man hasn't been arrested, the New York City CBS affiliate reported.

Faughey, 56, was killed inside her office at East 79th Street and York Avenue shortly after 9 p.m. local time on Feb. 12, WCBS said.
