Ian Whiffin is a digital intelligence expert at Cellebrite, which contracts with law enforcement agencies to examine cell phones and other digital devices. He testified in Lindsay Clancy's trial today (Monday, August 17, day 14 about what he found when he searched an extraction of her cell phone contents after she killed her three children in January 2023 in Duxbury, Massachusetts. Whiffin also testified in Karen Read's trial. You can watch his testimony from April 28, 2025, here: https://www.youtube.com/watch?v=bhbV5sMKaIs Whiffin testified about what Clancy's Apple Health data says about her movements, including at the time she killed her children after sending her husband to a restaurant and pharmacy. 02:11 "There are several tools within our catalog. One of them is designed to extract as much data as possible from a cell phone, and then one of the other tools is designed to take that extracted data, decode it, decrypt it, make sense of it, and provide it to the user in a way which can be searched, filtered, organized, reported, and presented." 05:01 "Now, you received a copy of the extraction for Lindsay Clancy's iPhone 13, correct?" "Correct." "And when you received that extraction, did you also want to know all the specific information about the case and the investigation?" "Typically, when I'm working the case, I don't want to know a lot of detail. I'd rather come to my own conclusions based on the data that I'm viewing, rather than you know note the intricacies of the case. All I require is an outline, the the date that something happened, the the time, who was involved, basic information." 07:45 "And what is health data, and and how is it? How does it show up on a phone?" "The user of the phone would be able to access the health data via the health application, where the information is broken down to explain how many steps have been taken over a particular period of time, the approximate distance that was traveled, the number of stair flights that were climbed. That data is stored on the device itself in a database. So, as a forensic examiner, I can take a look at that database in its raw form, understand exactly where that information is coming from, and present it to the user of our forensic tools in a slightly more forensic-friendly method than the user of the application on the phone would see. 09:05 "So, heart rate data comes from wearing an Apple Watch or a similar device, not from the phone itself. In the case of this phone, there was an Apple Watch paired to the device, and all of the heart rate data, which is recorded periodically throughout the day, is stored within the health database." 11:40 "And what was the the last time a heart rate was recorded from the watch to the defendant's phone?" "So the last heart rate recorded was at 1723 52. So 23 minutes past five in the afternoon, with a heart rate of 57 beats per minute." 19:24 "Going to page eight of your report, we have here at the top of page eight. Does that show the last flight client recorded on either the defendant's phone or watch." "It does. It shows that there was additional flight climb events logged by the phone, which were not logged by the watch at 17:03 and 17:33." "So these records indicate that at 5:03 p.m. the defendant's iPhone. Was with the person as it went up the stairs, and then at 5:33 p.m. the iPhone was with the person as it went up the two flights of stairs." "Correct." "And there's a time difference there. The start time is 5:33 p.m. and the end time is 5:38 p.m. for two flights of stairs, so that's roughly five minutes in between the two flights. Is there a way to explain that that length of time?" 20:28 "So in this case, it would have recognized that there was a flight climb on the phone at around 17:33:34, and a second one at around 17:38, 33, and it just grouped them both into one event. It doesn't mean that it took five minutes to walk up two flights of stairs. It's just within that five-minute period, there were two flight climbs." 23:10 "And basically, here you list various searches that occurred on each day between January 10 and January 24 from the extraction. Is that correct?" "That's correct. Broken down by day, with the time of the search, the website that was visited, the title of the web page, and then the identifier in the database." 23:57 "There was a search in the title. It says, "How quickly does Wellbutrin work for depression? Is that the title? Is that what the user is putting into the search?" 29:52 "And were you able to compile the messages that were sent and received between the defendant and her mother? And the defendant and her husband on January 24, 2023?" "I did, yes." 40:01 "And then, did you create a timeline combining all the data that we've talked about into one timeline?" "I did, yes."
