Michael Limburg

A 46-year-old Lawrence was sentenced Tuesday to life in prison without the possibility of parole for at least 25 years for multiple counts related to child pornography, Douglas County District Attorney Charles Branson said.

Michael J. Limburg was convicted in April of 10 counts of promoting sexual performances and four counts of possessing child pornography following an investigation into the case in 2012, Branson said.

During a preliminary hearing in 2012, a Johnson County Sheriff’s Office detective testified about discovering Limburg’s Internet Protocol, or IP, address during a search of child pornography videos and photos on an online file-sharing program.

The detective described several of the videos as displaying children engaged in sexual acts. Because the IP address belonged to a Lawrence man’s account, the detective contacted the Douglas County Sheriff’s Office, which seized Limburg’s computer and several floppy disks via a search warrant.

A Douglas County Sheriff’s Office detective later testified that images of child pornography were found on the disks and that a forensic examination of Limburg’s computer turned up numerous searches for terms associated with child pornography.
