The political career of Brownsville Assemb. William Boyland, a six-term Democrat who inherited a family dynasty in one of New York City's poorest neighborhoods, abruptly ended Thursday as he was convicted on all 21 counts of corruption charges in Brooklyn federal court.

Boyland faces more than 100 years in prison and stands to automatically lose his seat after jurors took about four hours to find him guilty of taking bribes to do favors for two undercover FBI agents posing as businessmen, skimming state funds from a nonprofit, and claiming $71,000 in phony travel expenses.

The 43-year-old assemblyman, whose uncle and father held the seat from 1977 to 2002, was brought down by evidence during the one-month trial that included secret recordings of him asking the agents for money and testimony from a former chief-of-staff.

Boyland put his hands to his face as the guilty counts were being checked off. He was remanded by U.S. District Judge Sandra Townes, who set his sentencing for June 30.

He is the 12th Albany elected official driven from office by a conviction since 2006.Boyland was acquitted in 2011 in federal court in Manhattan on charges that he took a no-show job in return for doing favors for a hospital company.

He was charged shortly afterward in Brooklyn with soliciting bribes to pay his legal fees in the Manhattan case. He took more than $13,000 in cash from the two agents and asked for an additional $250,000 in return for help with carnival permits and a real estate deal, according to testimony and tapes played in the Brooklyn case.

He was also convicted of two other schemes -- using state-funds that he funneled to a nonprofit in his district to buy T-shirts, sponsor boat trips and provide other help to his political campaigns, and claiming thousands in per-diem expenses for work in Albany on days when he was not in Albany.
