A 21-year-old Brooklyn man convicted of kidnapping a young girl was sentenced today to 10 years in prison despite his pleas for "mercy and leniency." Bernard Mutterperl wept before a judge, pleading that he needed help "outside of jail" as punishment for the Mother's Day 2007 incident in Midwood where he followed Xochil Garcia home and grabbed the girl, who was then 11. But the judge fell on the more stringent side of sentencing that could have fallen anywhere from 3 1/2 to 15 years. Garcia, now 13, testified at the trial this spring and spoke again in court today, recounting how she has suffered panic attacks and feared going out alone. She looked at Mutterperl and said, "You messed up my life. Some people want to fight me for no reason. Some people want to be my friend so they can be on TV ... I do not have any real friends now because of this."
