At least, that’s what a civilian expert of the Service de Police de la Ville de Montréal (SPVM) described 10 days ago in the most accurate testimony given at the trial of Giovanni Presta Jr., accused of premeditated murder of the biker.

Past investigations have shown that organized crime figures attach a GPS tag under their target’s vehicle to track them.

According to evidence filed at trial to date, two GPS beacons were mounted under the black Jeep Cherokee rented by Sebastien Beauchamp; The first was on November 28 and the second was on December 17. One of them was found by the police, but the other was not.

Various SIM cards recovered from Presta and from the accused, Frederick Silva, were occasionally inserted into these beacons and the phones used to track the motorcyclist.

Using cell phone records, SIM cards, device-specific numbers (IMEI) and communications tower records provided by phone companies, civil expert Mathieu Charest, SPVM’s strategic adviser, created a 400-page PowerPoint-style document. Symbols.

The document simultaneously retraces the path of Beauchamp’s vehicle, the movements of the white Malibu — equipped with GPS and probably used as a surveillance vehicle — and the path of a person on foot or on the metro. , who has an executive phone and who requests fixed beacons under the biker’s SUV.

The document shows all incoming and outgoing messages that beacons send to each other and the admin phones that query them.

A few hundred meters

So we see that the white Malibu drove around Beauchamp’s rented vehicle on December 6th, 14th, 17th and 18th before finding himself on December 20th at 2:30 p.m., very close to the location, when Sébastien Beauchamp was there. The shooting occurred in the parking lot of a gas station at the corner of boulevards Langelier and Robert in the borough of Saint-Leonard.

These days, simultaneous with the movements of the white Chevrolet Malibu, there are communications between an executive phone, the first beacon, and the stationary under the biker’s SUV.

On December 6, at 4:50 p.m., Sébastien Beauchamp’s vehicle and a Chevrolet Malibu were very close together in Montreal-Nord.

On December 14, at 3:21 p.m., the two vehicles were less than a kilometer apart, in the area of ​​rue Jarry and rue de Chamilly in the Saint-Léonard borough. This situation is similar to that which arises during the murder six days later.

On December 17, at 10:25 p.m., a communications tower operator telephone controlling the first beacon mounted under Beauchamp’s vehicle indicated that the motorcyclist’s vehicle was in the same location at the corner of Sherbrooke and Perry streets in the Center-Suite area. District of Montreal.

Over the next few seconds, the phone operator interrogates the second GPS beacon several times and says it is stuck under the victim’s vehicle.

The analyzes also show that on December 20, starting at 2:53 p.m., shortly after Beauchamp’s murder, one of the men involved made three calls to a taxi company. During the first call, he gave the address of 71 Duke Street in Montreal as his destination before changing his mind.

Each time the taxi will be displayed at the destination to pick up the customer.

That same day, after the biker’s murder, the Chevrolet Malibu took refuge at a Carex warehouse at two car washes in Terrebonne.

Sébastien Beauchamp’s killers wanted to mix the cards with technology by regularly changing the SIM cards and inserting them alternately into different GPS beacons and different cellphones. But eventually they caught up with her.

The trial resumes Monday with cross-examination of civilian witness Matthew Charest.

Subsequently, M.^e Advocate Antoine Piché and M^e Dominique Shufi, defense, should start their demands.
