SAGINAW TOWNSHIP, Mich. -- More than a dozen Polaroid pictures of graphic child pornography was discovered by a cleaning company in the bathroom of a local park.

Workers at R.B. Satkowiak City Sewer Cleaners of Carrollton Township found the photographs while clearing a sewer drain at Imerman Memorial Park in Saginaw Township on May 27.

Pat Kinney said his crew pulled about 15-30 pictures portraying sex acts between a middle-aged woman and a boy from a suction cleaning pump after the tool became clogged.

“They were tied together with a string,” Kinney said. “Just about everything you could think of was shown in the pictures.”

Kinney told TV5 the photos were of a woman most likely in her 40s having sex with a 5-or 6-year-old boy.

Kinney’s boss, Tom Satkowiak, turned the photos over to Michigan State Police.

He claims troopers told him the photos were unusable because they were dated and damaged by fecal matter from the toilets.

Satkowiak disagrees.

“The lady’s picture could have been put on the news; I’m 100 percent sure she could have been ID’d,” he said.

Officials from MSP Bridgeport Post wouldn’t comment, only saying they are investigating the case.
