"I was walking back from the mailbox when I heard a rustling sound in the woods. A raccoon came charging out of the woods at me. I tried to run but he caught up to me and bit my leg."

While walking in her yard during daylight hours, a raccoon (whose whereabouts are currently unknown) raced across the lawn to bite her.
