UPDATED — Sept. 24, 10:15 p.m. ET: St. Louis Post-Dispatch crime reporter said that in total four police officers were inured during Tuesday's unrest, when rocks were thrown at cops.
One of two memorials to slain Ferguson, Missouri, teen Michael Brown was discovered burning early Tuesday morning on the street where he was killed. It was not clear how the fire started.
Video captured the fire at the Brown memorial on Canfield Drive.
Even though it was still unclear how the fire started, the destruction of the memorial has broken the calm in the city.
Gun shots were fired in the community Tuesday evening, Alderman Antonio French said on Twitter.
Police responded to the incident quickly:
Protesters were heard chanting, "We want an indictment," in reference to Darren Wilson, the Ferguson police officer who fatally shot Brown.
The 10 days of protests and violence following the shooting has cost St. Louis County more than $4 million, Garry Earls, the county CEO told KMOV-TV Tuesday.
Earls said $2.6 million will be used to pay for police overtime, $1 million for Ferguson residents, $170,000 to repair damage to police vehicles caused by protesters, and another $146,000 for food and supplies for first responders.
