West Bloomfield Police Investigating Security Breach

detectives are investigating the possible theft of computer cards used to count votes from at .

The missing cards, about 25 in number and resembling the size of playing cards, should not comprimise the integrity of the Aug. 7 primary, Township Clerk Cathy Shaughnessy said.

Backup cards were previously programmed and will be available to use. The security of ballots were not compromised.

Chief Michael Patton said that Shaughnessy filed a report Wednesday after the cards went missing from a secure area, overnight between July 10-11. 

"There were no signs of forced entry in the building or the immediate area in which the cards were kept," Patton said Thursday.

"We're looking at who has access to that area. What we know so far is there are a number of department heads and other officials who have had access. We'll interview those people."

According to a release issued Thursday by Shaughnessy's office, the missing cards were being pre-tested on Tuesday afternoon.

"Only sworn election workers have daily access to the area where election equipment is stored," Shaughnessy wrote. "However, other Town Hall officials have access for emergency purposes. We have already made changes restricting even that access."
