Mileke Card was a good Samaritan with bad intent, police say.
Card, 19, came to the aid of a woman who was being mugged Friday at a Bronx subway station. But after he stabbed the purported mugger during a scuffle, Card was arrested and charged with attempted murder, police said.
The arrest stunned Card's family, which described him as a hard-worker who held a job while pursuing a high school equivalency diploma. The son of an immigrant from Belize had no police record.
Badilio Morales, 25, the man charged in the attempted mugging, had seven arrests for drug possession, grand larceny and burglary and was a fugitive who fled a larceny sentence.
Police said Nicole Evans, 40, of Manhattan, had just walked down the subway steps when Morales grabbed two chains from her neck.
Card came to her aid. When Morales began scuffling with him, Card told his family, he pulled a penknife and stabbed Morales twice -- in the neck and head.
Card then returned the two chains to Evans and began walking home. He was arrested about two blocks from the station.
Morales was charged with robbery.
