Police in San Antonio say a 19-year-old man was shot and killed over cough syrup.

FOX's Kevin Battle reports:

It's called "lean." That's the street name for a prescription cough syrup mixture that people use to get high and it was a dispute over lean that San Antonio police say lead to the murder of 19-year-old Brett Gorecki.

They say five other teenagers were meeting Gorfecki in a parking lot to pick up a dozen bottles of lean and they decided to rip him off, shooting him in the back as he ran away.

Then stealing his back pack containing police say, heroin methamphetamines and a gallon of the prescription cough syrup, which contains Codeine.
