The U.S. Drug Enforcement Administration has refused for more than two years to allow its agents to cooperate with a Los Angeles Police Department investigation into the death of a drug suspect shortly after he was arrested in a DEA operation, according to LAPD records.
The LAPD's homicide investigation has effectively stalled, and officials said in documents reviewed by The Times that without assistance from the DEA they cannot determine how the man's fatal injuries were inflicted.
