Los Angeles police and city officials announced two $50,000 rewards Tuesday for information leading to an arrest or arrests in connection with a pair of unsolved killings, authorities said.

The rewards were being offered in the deaths of Michelle Lozano, 17, and Bree’Anna Guzman, 22, according to a news release from the Los Angeles Police Department.

Both women’s bodies were discovered near freeways less than 10 months apart.

“We know that there are people out there that know something and we just need their help,” Anne Flores, a relative of Lozano’s said.

Lozano’s body was found near the southbound 5 Freeway in Boyle Heights in April 2011, according to the Los Angeles Times’ Homicide Report.

She had been wrapped in plastic and stuffed into a container, which was dumped over a concrete barrier along the freeway, according to the report.

Guzman, a mother of two, made a stop at a Lincoln Heights pharmacy to get some medicine when she disappeared the day after Christmas in 2011, according to her family.

She was found dead about a month later near a freeway on-ramp in Echo Park.

It did not appear the two victims knew each other, according to Capt. William Hayes of the LAPD.

Investigators, citing forensic evidence, announced that they believe the same person was responsible for both slayings.

However, officials said that with no surveillance video, eyewitnesses or a description of the killer, they have little to go on.

Hoping to generate fresh leads, investigators along with grieving family members addressed the media in front of the Police Administration Building in downtown L.A. on Tuesday.

The rewards, totaling $100,000, were being sponsored by Los Angeles City Councilman Gil Cedillo, according to the release.

“No one wants to bury a loved one, but worse than that is to bury your child who a was victim of crime. A cowardly crime,” Cedillo said.
