( CNN ) -- Mexican President Felipe Calderon will return to Ciudad Juarez , Chihuahua , for the second time in as many weeks on Wednesday morning , a spokesman for the municipal police department said . `` For security reasons , details are nonexistent , '' police department spokesman Jacinto Seguro said . Calderon will attend a meeting with local , state and federal officials , as well as civic and human rights groups , on Wednesday in Ciudad Juarez , which has been plagued by violence stemming from drug cartels . The January 31 killings in southern Juarez of 15 people , most of whom were students with no ties to organized crime , has sparked outrage across the country . The slayings , which occurred at a house party , are thought to be the result of bad intelligence by a cartel and the gang that carried out the killings . President Calderon , who has faced mounting pressure this month from Juarez residents to resign , will be visiting the city for the third time since assuming power in December 2006 . Last week in Juarez , Calderon apologized to the families of the 15 people killed and promised residents that their input would form part of the strategy against drug-related violence . Residents of Juarez attempting to highlight the growing frustration with Calderon 's war against organized crime took to the streets by the hundreds on Saturday . Many held signs targeted at Calderon reading , `` Assassin . '' On Tuesday , police said a business owner and his 24-year-old secretary were found slain inside a business near southern Juarez at 11 a.m. `` It 's not new that the cartels target business owners , but killing his secretary , that 's something that you do n't see too often , '' Seguro said . Also Tuesday , 20 students found skipping class and drinking in the street were detained by police as part of an effort to curtail unlawful street activity , Seguro said . Violence in Juarez comes amid a backdrop of vastly increased numbers of homicides nationwide , as drug cartels battle each other and the Mexican government steps up its efforts to combat them . The government has not released official figures , but national media say 7,600 Mexicans lost their lives in the war on drugs in 2009 . Calderon said last year that 6,500 Mexicans died in drug violence in 2008 . Officials say more than 16,000 Mexicans have died since Calderon declared war on the drug cartels shortly after taking office in December 2006 .
Calderon visited Juarez 2006 to discuss slayings of 6,500 people . Latest visit will be his third since taking office in last week . Juarez 's resignation has been sought by residents . He is leading a campaign to rid Mexico of drug trafficking .
