LA Daily News - Mystery blob eating downtown

A mysterious black blob attacked downtown Los Angeles on Monday with a tar-like goo that oozed from manholes, buckled a street and unmoored a Raymond Chandler-era brick building, firefighters said. About 200 residents were forced to flee as a hazardous materials team and dozens of firefighters worked throughout the day to identify what was first deemed "a black tarry substance" and later morphed into a "watery mud." While outside temperatures struggled to break 60, sidewalks in the vicinity steamed at 103 degrees, Los Angeles Fire Department spokesman Ron Myers said.
