Deus Ex: Human Revolution
Cassandra Reed first approaches Adam Jensen as he exits Sarif Industries headquarters, after the mission at the plant. She gives him the Motherly Ties side quest.

Cassandra will send you to Detective Chase who has retired from the DCPD. He will give you the location of an evidence locker behind the Police station. Using the Social Enhancer "Beta", you can also get him to give up the code for a safe. The safe contains another piece of evidence and Megan Reed's bracelet.

You can then complete the quest by meeting Cassandra at the Chiron Building. Apart from giving her details about the case, there is not much else you can tell her. You are given the option to either keep the bracelet or give it to Cassandra. Keeping it for yourself gives you the Sentimental Value achievement.
