(CBS/WCBS) MEDFORD, N.Y. - Neighbors of David Laffer said they're in disbelief that the 33-year-old has been arrested and charged in the pharmacy massacre that left four people dead on Sunday.
Neighbors told CBS affiliate WCBS that Laffer looked like a happy man when he married his wife Melinda Brady, who called Laffer her "best friend" and "soulmate."
The picture of the couple Thursday was quite different.
Laffer was arrested Wednesday on charges of murder and resisting arrest for the execution-style murders of four people at the Haven Pharmacy in Medford.
Laffer's situation changed considerably in recent years - enough that police said he was the man so desperate for prescription pills that he turned to murder to get them.
The allegations stunned many neighbors who knew the former Army private.
"I can't believe it; I can't," Carmen Montero told WCBS. "I'm shocked that this could possibly be David."
Cheryl Stephen said she still can't believe this accused cold-blooded killer lived right down the block from her parents in the house where she grew up.
"It's just very unsettling. Of course you feel better that he's caught, but it's like you don't know who your neighbors are. It's unbelievable," said Stephen.
Since the murders, Stephen says she just doesn't feel as safe.
