The Dallas news reported an ex-employee of the Christmas Light Company was shot to death by a current employee. Apparently, the ex-employee returned with a gun to settle a dispute and was shot to death by a current employee who also had a gun.
This company installs/removes Xmas lights. See http://thechristmaslightcompany.com This is a high-end company which provides, installs, removes, and stores the lights with a $500 minimum. They list phone numbers of (214) 515-XMAS (9627) and (214) 275-9627. Their Atlanta and Denver territories are available and they invite investments and business opportunities.
I don't know if this company is in any way associated with any of the several spammers who plaster the roadsides with "We Install/Remove Xmas Lights." The biggest multi-year offender uses a voicemail at 214-834-1414.
