INQUIRY PRESSED INTO KILLING OF 4 LINKED TO DRUGS
Federal and city law-enforcement officials yesterday questioned dozens of possible witnesses and sifted large caches of drugs, weapons and money in a widening investigation of the execution-style murders of a Colombian couple and their two infant children in Queens on Saturday. While agents of the Federal Drug Enforcement Administration pursued aspects of the inquiry in Colombia, scores of homicide and narcotics detectives focused the main investigation in Queens at the roadside scene of the slayings and at the victims' apartment, where $15 million worth of cocaine, $1 million in cash and an arsenal of weapons were found. The police said the slayings appeared to be related to a flourishing traffic in cocaine from Colombia. But positive identification of the victims had not been ma de, and the authorities were unable to say whether the couple might b e linked to any known drug ring or to mounting violence in the coca ine traffic in Queens inrecent months.
