BROOKLYN - A deadly rampage that occurred last week has led authorities to advise Brooklyn residents to treat stalking with urgency and to have it resolved before it potentially escalates.

"Don't keep it quiet," says Wanda Lucibello, who heads the special victims unit of the Brooklyn district attorney's office. "Treat it like you would treat a medical emergency."

Friends of slain Brooklyn resident Yelena Bulchenko say Maksim Gelman kept pursuing her even though she continually rejected him.

Gelman is accused of going on a 28-hour stabbing spree through New York City that left four people dead, including Bulchenko and her mother.
