No, but thrift stores are BIG here. The Salvation Army has many stores in a 20 mile radius as does the good will. Also there are lots of private second hand shops.
The shirt could have been sold at one of those to someone outside the area that was here, and something happened to cause their demise.
Unfortunately, with the proximity to NYC and PHL a lot of drugs pass through this area. If you ever heard of Rick Luytjes of Air America, this was where he ran drugs through.

In the early 1980s, Rik Luytjes gained two sterling reputations. One was as an upstanding businessman and pillar of the community. The other was as the most successful cocaine smuggler in US history. Over a four year period, he flew ten tons of coke, worth over twenty billion dollars, into the country.
So there can very easily be a drug connection to this case.
