A 30-year-old Burlington man has been sentenced to federal prison after computer detectives tracked child pornography to his computer.

Thirty-year-old Chad Michael Lee Welsh has been sentenced to 100 months in a federal prison, followed by 10 years of probation.

An undercover investigation tracked child pornography to an I-P address that ultimately was tracked to Welsh’s computer. Prosecutors say a search of Welsh’s computer found additional child pornography and many of the images were of children listed on the missingkids.com website as "missing" or "exploited."

Investigators says Welsh "received and distributed" child pornography via computer software called LimeWire.
