Police led a man and a woman out of a home in Medford after executing a search warrant in connection with the pharmacy slayings that happened over the weekend.
The man charged with killing four people during a drug holdup at a Long Island pharmacy is now represented by Amy Fisher's former attorney.
Newsday says Eric Naiburg will defend David Laffer, who has pleaded not guilty to first-degree murder charges.
A teenage Fisher pleaded guilty to shooting Mary Jo Buttafuoco in the head in 1992. The victim's husband, auto body shop owner Joey Buttafuoco, served jail time for statutory rape in the headline-grabbing case.
Naiburg's other high-profile clients have included Richard Angelo, a nurse known as the "Angel of Death.''
He was convicted of killing four patients with lethal injections in 1987.
