  Guatemalan police search for 'massacre' suspects
  Report: Police and military clash with suspected drug gang members
  Guatemala City (CNN) -- Guatemalan authorities were searching for suspects Monday, a day after security forces found 29 workers slain on a farm in a northern border province.
  Police and military combing the area spotted two abandoned Hummers and clashed with suspected drug gang members in several locations, while forensic investigators in Peten province worked to identify the victims, CNN affiliate Noti7 reported.
  Authorities said they believe the Zetas drug cartel could be responsible for Sunday's killings, state media reported, citing national police director Jaime Otzin.
  At least three teenagers were among the victims, according to the state-run Guatemalan News Agency, which described the killings as a "massacre."
