A 16-year-old Buffalo youth has pleaded guilty to second-degree murder for killing a deli owner during a robbery.

Robert Gwynn was 15 when he and a 13-year-old accomplice robbed Myheeb's Deli in November. Gwynn shot the deli owner, Mike Saeed, in the chest. He died soon after.

Because of his age, Gwynn was prosecuted as a juvenile offender. State Supreme Court Justice Timothy Drury told him he'll likely impose a sentence of eleven years to life when he is sentenced in July.

The 13-year-old is being prosecuted in Family Court. His identity hasn't been released.
