Cold Case Review - Private Investigation Toronto
The ISN Team has been called on to review and re-investigate cases that have long ago been closed by the authorities and where no further action is being taken. The reality is that new technologies and science are continually emerging and as witnesses mature they are often more likely to speak about incidents they were involved in. When a case is not solved there are often many victims who cannot have closure until they know what has happened. ISN investigators will work with individuals and organizations to review and if necessary re-investigate cases that have been closed. ISN associates are experienced in the latest science and technology in investigations and will work with you to ensure the best possible investigation is done.
No matter what your problem or need ISN will find a solution that will work for you using
the best people, the best methods,
achieving the best results.
