A Centers for Disease Control and Prevention technician may have been exposed to live Ebola virus after a laboratory error discovered on Tuesday. The CDC will also check whether other employees were exposed to the virus and will monitor the exposed technician for 21 days, the length of the disease's incubation period. The exposed technician was reportedly wearing a smock and gloves, but no facial mask. http://on.mash.to/1A6PLMV http://bit.ly/1fJ5yqZ

According to police the Berkeley, Missouri, police officer who shot and killed 18-year-old Antonio Martin at a gas station on Tuesday didn't have his body camera on at the time. The teenager allegedly pointed a gun at the officer before the officer shot him. Though the publicly available surveillance video of the incident might support that claim, it's difficult to discern. That may mean that much of the investigation will depend on the recollections of the officer and other eyewitnesses, echoing the case of Michael Brown in nearby Ferguson, Missouri. http://on.mash.to/1t07Q92 http://bit.ly/1fJ5yqZ
