The man suspected of killing 77-year-old Dallas Ayers, a well-knownChronicle newspaper vendor, was charged with murder after the District Attorney dropped the original charges against him.
According to press reports, Mark Anthony Cassell, 36, was charged Friday afternoon with murdering Ayers, who the Chron described as a "quiet and amiable man who spent his weekdays selling The Chronicle from a booth in the concourse of BART's Montgomery Street Station."
The District Attorney's Office says Cassell committed elder abuse against Ayers, who was standing outside the station on the morning of Jan. 28 when Cassell allegedly lifted him into the air and dropped him onto the sidewalk.
Ayers died from his injuries three weeks later.
Police arrested Cassell last week, but the District Attorney's Office dropped the charges two days later, claiming there wasn't enough evidence -- yet. Investigators have since found new evidence, according to the DA's Office.
Cassell will be arraigned this week.
