Much about her remains unclear, but here is what CNN has learned from at least one source:

The second of three children, Neda lived with her parents in a middle-class neighborhood east of Tehran.

She was a happy, positive person. Though she studied philosophy and religion at the Azad Islamic University, she was more spiritual than religious. She also loved music. She once studied violin but had given it up and was planning to take up piano next. She had just bought a piano, but it had not yet been delivered.

Her demeanor was typically calm, even serene, but she had a quirky, playful sense of humor. A friend recalled that once, when Neda was visiting her friend’s house, she picked up a white Teddy bear, took off her big, purple-studded earrings and put them on the bear. Then she removed a necklace from around the neck of a friend and put it around the bear’s neck, taking delight in the bear’s transformation.
