A Northampton man is facing a child endangerment charge after allegedly attempting to exchange his baby for two 40-ounce beers at a Chicopee truck stop Monday afternoon, Chicopee Police said this morning.... Matthew Brace, 24, of Northampton was pushing his 3-month-old daughter in a stroller when he approached a man who was repairing an air compressor, said Chicopee Deputy Police Chief William Jebb. “Mr. Brace picked up the stroller and put it inside the [man’s commercial work] truck along with the baby and asked for two 40s,” Jebb said. The deal was no joke.
