PM Environmental, Inc Joins Livingston County Sheriff Cold-Case Team to Locate Missing Person

PM Environmental, Inc (PME) has recently joined the search efforts of the Livingston County Sheriff Cold-Case Team in their mission to locate missing Okemos teacher Paige Renkoski.

Enlisting the help of Ground Penetrating Radar (GPR), the Cold Case Team and PME investigated the grounds of burial sites for the remains of Renkoski, who has been declared missing since 1990. The search teams were able to find bones in a pond area in Handy Township, located off Nicholas Road south of Grand River Avenue, but it has been stated by Mike Frayer, member of the cold-case team, that discovered bones were likely to belong to animals. “It's not unusual to find stuff like this in an area like this, but I'd rather bag it and tag it and make sure," Mike said.

According to William Lenaghan, member of the cold-case team, a dive team will explore the Handy Township pond, a body of water that has experienced receding levels of water over the years as indicated by a 1989 map.

PM Environmental, Inc. owns and operates the latest Ground Penetrating Radar (GPR) Unit equipped with a 400 MHz antenna and a powerful datalogger/software package that detects and maps utility pipes, shallow engineering structures, and performs numerous environmental applications. PM Environmental, Inc.’s staff has received extensive training in the use of this equipment. For more on Ground Penetrating Radar, visit: or
