Daytha Holmes was sleeping when a car slammed into a tree outside her house at the corner of California Street and Allston Way early Friday.
Today, Holmes walked across to the street to place flowers at the site in a growing memorial to a Milanca Alicia Lopez, a young mother who lost her life in the collision.
"We heard a big crash, and then we heard moaning," she said.
The neighborhood was quiet today as friends and neighbors stopped off with bouquets. One card read simply, "Milanca Alicia Lopez."
The roundabout does little to slow traffic, she said, and did nothing to prevent the accident. The Cadillac in which Lopez and her son Xavier were riding slammed into a tree around 1:10 a.m., killing the Cal grad and dealing serious injuries to her son and the male driver, who remain hospitalized.
A candlelight vigil is planned for 5 p.m. Sunday at the site, which borders a neighborhood park.
