New Mexico state Sen. Carlos Cisneros dies

SANTA FE (AP) — The Legislature's lead attorney says long-serving New Mexico state Sen. Carlos Cisneros of Questa has died.

Cisneros's death on Tuesday morning was confirmed by Legislative Council Service Director Raúl Burciaga and a spokesman for the Democratic Senate majority caucus. Caucus spokesman Chris Nordstrum says Cisneros had a heart attack.

Cisneros served 35 years in the state Senate starting in 1985. The Democratic lawmaker played a leading role in annual budget negotiations about state government spending as well as legislation on tax policy.

Cisneros represented a vast Senate district that stretches from the state line with Colorado to the outskirts of Los Alamos, including the communities of Taos, Peñasco, Truchas and Pojoaque Pueblo.

State leaders released statements after learning of the senator's death Tuesday.
