(United States v. Juan Olaya, D-2, Case No. 15-cr-20200, EASTERN DISTRICT OF MICHIGAN SOUTHERN DIVISION)
On December 5, 2014 a group of 6 that was attached to a spree of home invasions was finally broken after arrests were made in a home-invasion in Flower Mound, TX. The group was attributed to home invasions in New Jersey, Michigan, and Texas and charges varied from federal racketeering to weapons, kidnapping and violent assault.
In Texas, one of the group’s members left a cell phone in a vehicle that was found to be associated with the crimes. According to court documents (linked below), Texas’ officer Mark Esparza obtained a warrant to examine the Samsung phone and photo documented a number of text messages and other evidence related to the crimes. The phone did not, however, have a full forensic acquisition. After photo documenting the evidentiary information, officer Esparza returned the warrant. Nine months after Esparza’s search, the FBI, without obtaining a new warrant, searched the cell phone again and this time they did a full forensic acquisition of the phone.
This final acquisition of the phone brought the number of searches of the phone to three: Pre-warrant search for IMEI and phone number, warranted search for the phone evidence, and Federal search through the acquired phone image. Presumably, the search through a forensically acquired phone would yield additional information, and reading between the lines I am guessing this was the case for the evidentiary Samsung phone. Certainly it would assist in authenticating the evidence.
Defendant Jaun Olaya, the owner of the phone and one of the group members charged, moved to suppress the results of all three searches. Mr. Olaya argued that “even if the screenshots that Esparza obtained should not be suppressed, the results of the more comprehensive FBI search should be.” On 4/19/2017 the Eastern District of Michigan, Southern Division court agreed with Olaya: The FBI’s acquisition of the phone and subsequent search was found to be warrantless and a violation of Olaya’s 4th amendment. Pages 14 through to the end of the Court’s opinion and order contain the Court’s reasoning on this point.
What would be interesting to me (and potentially to criminal defense attorneys) is whether the same logic of the court could be applied if officer Esparza HAD done a full forensic acquisition of Olaya’s phone: Under those conditions, would the government’s use of Esparza’s acquisition required a second warrant? The fact is, there is a lot of data in a phone acquisition that has nothing to do with specific crimes so I am guessing that the argument could be made. If any criminal attorneys know of some good cases to answer the question, feel free to post below!
