For the first time, Baltimore police have begun investigating overdoses in an effort to trace drugs back to dealers, joining a wave of Maryland law enforcement agencies showing up at 911 calls previously left to medics, reports the Baltimore Sun .
A task force of five detectives will operate out of the homicide unit, responding when possible to fatal and nonfatal overdoses. More than 1,000 patrol officers also are being trained to respond to overdose scenes by the federal Drug Enforcement Administration.
