12-Year-Old Boy Left For Dead Flags Down Motorist
A 12-year-old boy with several stab wounds was found wandering near a Brooklyn highway Saturday, officials said.

Luis Martinez was spotted by a passerby wandering near the Jackie Robinson Parkway in Cypress Hills around 9:10 p.m. Sources say he was staggering away from Highland Park after being left for dead, trying to flag down a motorist.

The boy was reportedly stabbed up to a dozen times, at least once to his chest, neck and back.

According to the Daily News, Martinez left his East New York home Saturday evening with a friend, but never returned. Investigators believe he snuck off and met with two friends -- a 15-year-old boy, and a 14-year-old girl -- to smoke marijuana.

The 15-year-old began arguing with Martinez, blaming the younger teen for getting him into trouble the last time they smoked pot, a source told the News. When Martinez fought back, his friend allegedly pulled out a knife and attacked him.

Martinez was rushed to Jamaica Hospital in critical condition, where he reportedly underwent surgery for a punctured lung and kidney. He remains in serious condition.

Relatives are still baffled as to how he ended up so far from home.

The 15-year-old has been arrested and charged with felony assault, police said. The girl was being questioned at the 104th precinct but has not been charged.

The investigation is ongoing.
