The arrest of a Mexican construction worker in Denver this week is being called a "major break" toward solving the murders of hundreds of women in the border city of Ciudad Juarez, Mexico, officials said.

Edgar Alvarez Cruz, 30, is believed to be linked to a gang of men who raped and killed several women between 1993 and 2003, and authorities said they expect him to lead them to other suspects.

Alvarez Cruz, who has a criminal record in Colorado dating to 2002, was arrested Tuesday by U.S. marshals at his girlfriend's home in west Denver.
He is being held by Immigration and Customs Enforcement officials in El Paso, Texas, as an illegal immigrant.

Maria Peinado, Alvarez Cruz's girlfriend in Denver, said Friday that his arrest was a case of mistaken identity and that he wasn't in Juarez when the killings he is accused of happened.

"And he doesn't have the resources to kill someone from here," said Peinado, 27. She said that her boyfriend moved to Denver from Juarez in 1999 and had not returned.

Antonio O. Garza Jr., U.S. ambassador to Mexico, was confident that authorities have the right man, calling Alvarez Cruz's arrest a "major break" in helping to solve the deaths of hundreds of women in Ciudad Juarez, a city that borders El Paso.

"We believe Alvarez Cruz's arrest will help U.S. and Mexican law-enforcement authorities solve numerous cases involving the murders and disappearances of women in Ciudad Juarez," Garza said in a statement released Thursday.

The slayings of more than 300 women, some of whom where found dumped in the desert, has terrorized the city for nearly 15 years. Police have arrested suspects, but some have been acquitted and others have died before they were sentenced.

Claudia Bañuelos, spokeswoman for the attorney general's office in the state of Chihuahua, said that two other men are in custody. Bañuelos said that Alvarez Cruz and the two men are being investigated in the deaths of eight women - ages 15 to 21 - whose remains were found in 2001 in a field near a road.

Bañuelos said that the Chihuahua attorney general would not comment on whether those eight slayings are linked to the hundreds of others.

Ken Deal, chief deputy U.S. marshal in Colorado, said they received information from Mexican officials in June that Alvarez Cruz could be in Denver.
Deal said that authorities kept surveillance on him until the U.S. marhal's office in Texas and a liaison in Mexico told them Alvarez Cruz could be in the country illegally and "that he was wanted for questioning with the homicides in Mexico."
