New York ? Gov. David Paterson has proposed roughly doubling New York’s DNA database to include samples from even low-level offenders, making it the first in the nation to so broadly collect and use that evidence to solve crimes and exonerate people wrongly convicted.

New York’s law would require adding about 48,000 samples a year to a laboratory system that state officials say is capable of handling the extra work, with no current backlogs.

State police now have DNA samples from 356,000 people convicted of felonies and certain misdemeanors, including petty larceny and endangering the welfare of a child. The database began in 1996 with the genetic material from killers and sex predators, and has been expanded three times.
