\section{Befund}

Two image files have been provided. One for Beth Dutton (Apple iPhone X) and one
for Heisenberg White (Galaxy Note10). Both images were analyzed with Cellebrite
Reader\footnote{sha1sum: 327cc80f3a477599ed2f62cb467677830405386a} and databases
of interest were opened using the DB Browser for SQLite in version 3.12.2. The
system used for forensic analysis is Windows 10.

Heisenberg has gotten in contact with Beth in July and tried to sell a 2014
Hyundai Sonata on craigslist. The conversation with a potential buyer is listed
in figure~\ref{fig:heisenberg-stolen-car}. The video Heisenberg recorded during
the arrest\footnote{/data/media/0/DCIM/Camera/20210720\_150222.mp4} (on
2021-07-20) indicates that the VIN is marked as stolen.

Heisenberg is subscribed to multiple topics on Twitter from which he regularly
receives E-Mail notifications. The Twitter App stores which topics its users are
interested in. For Heisenberg, the database named
1378525099184291843-61.db\footnote{/data/data/com.twitter.android/databases/1378525099184291843-61.db}
contains information on his interests in the table \emph{interest\_topics}.
Furthermore, he has an android app called \emph{HideX} installed (see
figure~\ref{fig:heisenberg-hidex-apps}) which allows users to hide information
on the phone or to restrict access to certain apps.

Beth has multiple conversations with her sister, Marsha Mellows, on her phone.
They have communicated using different Apps such as Signal, WhatsApp and
Snapchat. Beth also has an E-Mail account called \emph{tornadobeth@gmail.com}
which receives daily E-Mails from Apple News. The E-Mail account is mostly used
for creating accounts for Apple.

Beth's chat history shows messages with Marsha Mellows, her sister, where the
topic is cars that could potentially be interesting to them. They use specific
language such as \emph{baby shark} or \emph{f0x} in their messages. Her location
history shows that she visited multiple cities between February 2021 and July
2021. In some cities she took pictures at the airport. Other pictures she took
include cars. She met with her friends for dinner at Amani's Byob Downingtown as
indicated by a
post\footnote{/filesystem1/private/var/mobile/Containers/Data/Application/AF3D3CB2-CFB9-4234-AEA7-16C92A99E024/Library/Caches/graphStoreDB/GraphStore\_100032893519941.sqlite3}
she made on Facebook on 2021-06-18 (see figure~\ref{fig:beth-dinner}). She also
connected her phone to a car MY-QX80 on
2021-04-06\footnote{/filesystem1/private/var/containers/Shared/SystemGroup/C272EF97-5B86-4578-B2ED-AAAB06943E85/Library/Preferences/com.apple.MobileBluetooth.devices.plist}
via bluetooth (see figure~\ref{fig:beth-connected-car}). On 2021-06-29 she
called her sister from New York. On the same day she took a
video\footnote{/filesystem1/private/var/mobile/Media/DCIM/100APPLE/IMG\_0079.MOV}
which has location information embedded inside. She did not use the Waze App on
2021-07-13.

\section{Gutachten}

Heisenberg is most likely aware that the car he was trying to sell was stolen.
His message that he will only share the VIN once they meet in person indicates
that he did not want to share it earlier out of fear that the buyer will see
that the car is marked as stolen. He was in contact with Beth as well and likely
received the car from her to sell.

Heisenberg's interests on Twitter include multiple cryptocurrencies, which are
listed in figure~\ref{fig:heisenberg-crypto-interest}.

Beth has been introduced to stealing cars by her sister Marsha Mellows. They
have completed multiple jobs in different cities at least from February 2021
until her arrest in July 2021. The online conversations both have contain
special words such as \emph{f0x} or \emph{baby shark} which could be code words
for different cars.

While Beth did not use the Waze App on 2021-07-03, she last used the App on
2021-07-01 at the Philadelphia International Airport (see
figures~\ref{fig:beth-waze-usage} and~\ref{fig:beth-waze-userdb}).
