The search for human remains at a Milwaukee home is over without any discoveries.
Police had been looking for remains at the home where convicted killer Michael Lock once lived, but investigators noted no evidence of value was uncovered.
The notorious drug dealer was convicted of homicide for the deaths of two other drug dealers in 2008.
Their bodies were found under concrete slabs of a home Lock once owned several years after they were killed.
Police believe there are more victims and obtained a warrant to search the yard of the home.
