(CNN) -- The apparently strangled bodies of two women who worked for a weekly newsmagazine in Mexico City were found Thursday morning in a suburb south of the city, officials said.
The bodies of Ana Marcela Yarce Viveros, 48, and Rocio Gonzalez Trapaga, 48, were found by police behind a cemetery in the capital's southern suburb of Iztapalapa, the city's Special Investigation Police Unit said in a statement.
Yarce was working as public relations manager and co-founder of the magazine "Contralinea," and Gonzalez was a freelancer for the magazine who had worked as a reporter for the television station Televisa, the magazine said in a statement. Gonzalez also operated a currency exchange business in the capital, it said.
Mexico City's attorney general's office said in a statement that the bodies were found around 7 a.m. and that both appeared to have been strangled. Forensics tests were being carried out, said the statement.
In a communique, Contralinea asked the authorities to investigate and bring to justice those responsible.
During Thursday's session, the Mexican House of Representatives observed a moment of silence in honor of the journalists.
Mayor Marcelo Ebrard said he would personally supervise the investigations.
