Yeung, a 26-year-old publicist who works for tech startup BitLit, received a "serious head injury". This landed her in hospital in critical condition and in a medically induced coma.
Friends are rallying to support Yeung and her family. They've already donated over $23,000 to an Indiegogo campaign in support of her recovery.
The Indiegogo page states: "The campaign amount is a number which we believe can be met, and, are hopeful will be greatly exceeded. The funds are not only for the short-term, but will be to help Ovey and her family through the long and arduous process of rehabilitation."
The campaign has a goal of $25,000 and closes on August 31. The proceeds will go to a trust fund being established for Yeung.
On Monday, police said they were looking for a "dark-coloured Honda Civic with probable front-end damage". Video obtained by police showed "several witnesses" to the incident.
