LOS ANGELES (CBSLA.com) — Police and the City Council Tuesday announced two $50,000 rewards for information leading to the arrests of suspects responsible for the murders of Michelle Lozano, 17, and 22-year-old Bree’Anna Guzman.

Detectives say both women, who did not know each other, were reported missing in 2011 in northeast Los Angeles.

“We’ve obtained forensic evidence that we’ve been able to examine and determine that it links both cases,” Capt. Billy Hayes said. “Again, I want to be a little bit cautious in what I say, but that forensic evidence has identified that the same individuals are responsible for this.”

The nude body of Lozano was found in April of that year inside a plastic container next to the State Street off-ramp of the southbound Golden State (5) Freeway in Boyle Heights.

Guzman, a Lincoln Heights native, disappeared while walking from her home along the 73000 block of Humboldt Street in December 2011. She was the mother of two children.

Her body was found a month later near the Glendale (2) Freeway on-ramp in Echo Park.

“I know that there’s people out there that know something,” a family member said. “We just ask that you please help us. Help us. Say something, because we need justice for this.”
