MEDFORD - Police are searching for the gunman who killed four people in a Medford drug store robbery yesterday.

Officials say that they have received a number of tips from residents saying they have seen the suspect, who was caught on a surveillance camera.

Suffolk County Police Commissioner Richard Dormer today said all four victims were shot "suddenly and quickly" and offered no resistance to the suspect, who ended up stealing only prescription pain killers from Haven Drugs on Southaven Avenue.

Among the four victims was 17-year-old pharmacist's assistant Jennifer Mejia, who was due to graduate from high school Friday. Also killed were pharmacist Raymond Ferguson and customers Bryon Sheffield, 71, of Medford, and Jamie Taccetta, 33, of Farmingville.

Police are asking the public for help in identifying the killer. Anyone with information is asked to call Crime Stoppers at 1-800-220-TIPS.
