Here's the language from the search warrant:
6. That while Officers were at Wells Lane, Almeida provided Dulos' cellular number, 929-499-7661.
Officer Coughlin called Verizon to ascertain when the telephone was last used and/or if Verizon could
"ping" it to get a location. Verizon confirmed that the cellular telephone was last active on May 24, 2019,
at 11:09AM and Verizon confirmed that the cellular telephone was last active on May 24, 2019, at 11:09
AM and that the last cell tower used by the "c ellphone was located at 4 Tower Drive in Darien -
approximately one mile south of Waveny Park.
7. That upon learning that Jennifer Dulos may have been driving her black Chevrolet Suburban
(Connecticut passenger registration AJ69099), officers began searching the area for the vehicle. Captain
Walsh located Jennifer Dulos' black Chevrolet Suburban (Connecticut passenger registration AJ69099)
along an isolated stretch of the southern portion of Lapham Road in very close proximity to Waveny
Park. This location was consistent with the Verizon "ping." A police canine was summoned to search the
surrounding area with negative results.
15. That investigators used cellular data from Jennifer Dulos' cellphone and residential surveillance to
construct a timeline for the crime which included the victim's vehicle leaving the driveway of the residence
and points along a route which led to Lapham Road, where the vehicle was ultimately recovered. Data
showed the victim's phone remained within the area of Lapham Road and the south portion of Waveny
Park for approximately forty minutes prior to its last known location. Approximately three minutes after
Jennifer Dulos' phone disconnected from the network, the suspect's vehicle was shown on surveillance
camera traveling northbound along the Merritt Parkway (Rt. 15) just north of Exit 37. This timeframe
illustrates a forty minute gap in which the suspect's location is undetermined.
