Danielle Greaves is one of the many Sims buried in Olive Specter's lot. She was the first Sim to die on Olive's lot, and died while Olive was a teen. She died of starvation. Danielle and Jessica Ebadi are the only Sims in Strangetown who can be resurrected in-game. She shares the same last name as Lotta Greaves.
What is even more odd is Danielle has an NPC type when viewed in SimPE and is treated as a pizza delivery woman. Because of this it is a strong possibility that she was meant to be the neighborhood's pizza delivery woman, especially due to the fact that there are only 2 pre-existing pizza deliverers in Strangetown when usually in pre-made neighborhoods there are 3.
According to her age data in SimPE, Danielle was 101 days from being an elder when she died.
