Goikoetxea started his activities in ETA in 2005 . Two years later , Txeroki ordered him and Jurdan Martitegi to form a new cell in Biscay . The cell , named '' Askatasun Haizea '' , was created in February 2007 , when ETA was still officially on a ceasefire . The first attack in which Goikoetxea participated was a car bomb attack against a Civil Guard barracks in Durango on August 24 , which left two police officers injured . This was ETA 's first attack after the end of the ceasefire in June . In late 2007 and early 2008 , Goikoetxea and the Biscay cell , carried out several attacks around the Basque Country , targeting courthouses or political offices . In 2008 , Goikoetxea placed three car bombs : in Calahorra , La Rioja on March 21 , in Legutiano , Álava , which killed a Civil Guard on May 14 and in Getxo on May 19 . He was at first believed to be the killer of Isaías Carrasco
