Police say sex offenders wore GPS monitors during killings
(CNN) — Two convicted sex offenders, who have been charged with raping and murdering four women in Southern California, were wearing ankle monitors at the time of the alleged crimes, police say.
"The GPS was in fact attached to these suspects during the commissions of the crimes," Anaheim police Chief Raul Quezada said Monday.
Steven Dean Gordon, 45, and Franc Cano, 27, were arrested Friday night, and police say their ankle monitors and the women's cell phone records helped authorities tie these cases together. Both men are expected to appear for arraignment Tuesday, authorities said.
"The utilization of GPS through our two suspects, that coupled with initial evidence, led us to those individuals," Quezada said.
According to Lt. Bob Dunn, both men were in compliance with their regular, required check-ins with police every 30 days. He said police had no reason to watch them more closely.
Both have been convicted of sex crimes with children: Gordon in 1992, and Cano in 2007.
All four women are believed to have died over the last six months.
The body of Jarrae Nykkole Estepp, 21, of Oklahoma was found at an Anaheim recycling plant last month.
The disappearances of three other women in Santa Ana are being treated as homicides, although their bodies have not been found.
Kianna Jackson, 20, was last seen in Santa Ana on October 6. Josephine Vargas, 34, was last seen on October 24. And Martha Anaya, 28, was last seen in Santa Ana on November 12.
All of the women are believed to have worked as prostitutes, police said.
