Mexico City prosecutor says suspect acknowledges being at apartment where 5 slain

1MEXICO CITY - A man suspected in the killings of a Mexican photojournalist and four women has acknowledged being in the apartment where the slayings occurred, Mexico City's top prosecutor said Thursday.
2Prosecutor Rodolfo Rios told the Televisa network that the suspect was one of three men whom surveillance cameras recorded leaving the apartment building on Friday.
3Rios declined to identify the man, who he said previously served nearly 10 years in prison for rape and causing injuries.
4Rios wouldn't say whether the suspect had confessed to either the killings or the robbery police say apparently was carried out at the apartment.
5The victims included Ruben Espinosa, a photojournalist who fled the Gulf Coast state of Veracruz because of intimidation.
6He was found shot in the head, his body bound and tortured.
7The attackers also killed his friend, activist Nadia Vera, and two of her roommates - a 19-year-old aspiring makeup artist and a woman from Colombia - as well as their 40-year-old housekeeper.
8Rios said investigators had not yet determined the motive in the killings, and that all lines of investigation remained open, including the possibility it could have been related to Espinosa's work.
