On October 12, 2010, Gonzalez was stabbed to death inside a bathroom at San Diego City College, according to police. Homicide detectives called it one of the most horrific crime scenes they had ever seen.
Gonzalez, who had given birth to her daughter Crystal months earlier, was studying to be a nurse.
A few weeks before Gonzalez's murder, Perez was accused of kidnapping her, and then beating and raping her for three days. But prosecutors declined to take the case, citing a lack of evidence.
After Gonzalez’s body was found, investigators quickly pointed the finger at Perez, who is said to be the estranged husband of Gonzalez.
Perez reportedly fled to Mexico after Gonzalez' death and it was believed that he had been there ever since.
After a 16-month-long search, officials said they arrested Perez Sunday at about 3:30 a.m. at Avenida Revolucion in Tijuana. Mexican authorities aided in the arrest.
Perez is set to be transported to Mexico City where he will be afforded an extradition hearing prior to being returned to the U.S., according to a media release.
