grounds to believe the telephone device is or will be used within

the geographical area over which the court has jurisdiction, or (c)

device is located within the geographical area over which the court

has jurisdiction.

The order issued under this section:

leased or in whose name is listed the telephone line

to which the pen register or trap and trace device is

to be attached,

subject of the criminal investigation,

c. the number and, if known, physical location of the

telephone line to which the pen register or trap and

trace device is to be attached and, in the case of a

trap and trace device, the geographic limits of the

trap and trace order, and

d. a statement of the offense to which the information

likely to be obtained by the pen register or trap and

trace device relates; and

for a period not to exceed sixty (60) days. Extensions of such an

order may be granted, but only upon application as provided in

Section 177.3 of this title and upon issuance of an order as

required by subsection A of this section. Each period of extension

shall be for a period not to exceed sixty (60) days.

of a pen register or a trap and trace device shall direct that:

register or a trap and trace device is attached, or who has been
