I just found something entirely new doing this elusive target. The egg was no problem, because Diana said in the intro it's in a locker, I did all the Escalations so I knew where they might be. To no surprises, I found it in Dalia's office, got it after distract one of the guards. Also, if you follow the target, he'll talk about the egg being on the top floor, and the security guards on the second floor talk about the egg as well.
OK, now the target, he is very easy to find despite the lack of info in the intro movie. His routine is somewhat random, he's route is set in location but out of order. I followed him for a long time, couldn't kill him because he's always close to the public. I put a sniper in the shed and smuggled it near the garden besides the bar, however, I cannot go any further with the gun because everyone would see me. I dropped it in the garden, and then, he and his body guard showed up. His body guard sees the gun and carried it to the weapon's box, left him alone in the garden, and that was the end of him. I totally forgot you can break AI routine by place a gun on the ground, if you know where the closest weapon's box is, you can plan out your attack accordingly. I should test on the "weapon's box" method in a normal mission. This game is very very good you guys!
@rikiguitarist: the problem is that DZ is going to be a huge part of your gameplay in the Division, it's not like a separate mode you can enter. So if you are a lonewolf, and you want to play the Division RPG style (get better loot), you are going to have a bad time in the DZ. I got screwed several times playing alone, while in a random matchmaking group, your teammates are not helping.
P.S Based on several hours of playing (lv 8 in the PVE, Lv 7 in the DZ), I find that the best way to approach extraction in DZ is get in and get out, sometimes there are invincibility frames while you are putting your loot on to the heli. So as a lone player, you can just run away once your loot is on the heli.
For all the lonewolves want to enjoy DZ out there, i think there are some tweaks that the developer can do to ensure some non-asshole players can also enjoy their lives in the DZ.
1. When a player turn rogue, he/she should automatically have some kind of stat debuff, like take away chunk of his/her health bar, less damage output, or slow health recharge .
2. Penalties once you turn rogue, stripe some of your funds depending on your rogue meter, take away your keys for the lootcrate, or you cannot extract for a certain time depending on your rogue meter.
3. Lock out vendor items to rogue agents for a certain time.
4. Better pairing people who generally just don't want to fuck with other players (probably not difficult to do, since server side can track how many players turned rogue in a certain region).
