PHILADELPHIA — An invisible killer has ended the lives of two people and sickened four others.
Police said that in separate incidents — one in Cheltenham Township, Montgomery County, and the other in Philadelphia — carbon monoxide, a colorless and odorless gas, snaked its murderous way through two homes.
Police, contacted by school officials when a 15-year-old boy didn’t show up for school Tuesday, entered a home on Central Avenue in the Cheltenham Village section of Cheltenham just after 5:15 p.m. and found the teen and a 50-year-old man dead in their bedrooms, apparently from carbon monoxide poisoning.
