City Is Amassing Trove of Cellphone Logs

The call records from the stolen cellphones are integrated into a database known as the Enterprise Case Management System, according to Police Department documents from the detective bureau. Each phone number is hyperlinked, enabling detectives to cross-reference it against phone numbers in other files.

The subpoenas not only cover the records of the thief’s calls, but also encompass calls to and from the victim on the day of the theft. In some cases the records can include calls made to and from a victim’s new cellphone, if the stolen phone’s number has been transferred, three detectives said in interviews.

 

Mr. Sussmann suggested that the Police Department could limit its subpoenas to phone calls beginning on the hour, not the day, of the theft, and ending as soon as the victim has transferred the number to a new phone.

According to documents reviewed by The New York Times, the police subpoenas seek call records associated with the telephone number of the stolen phone.

As a result, three detectives said in interviews, the phone companies’ response sometimes includes call records for not only the stolen phone, but also the victim’s new phone, depending on variables like how quickly the victim transfers the old phone number to a new handset and how many days of calls the subpoena seeks.

Interesting.
