At a heavily guarded hospital in the northern Mexican city of Monterrey, former
                 Mayor Alfonso Martinez Dominguez sat in a wheelchair Monday as officials read
                 him a list of 95 questions.

                 Outside, security guards surrounded the hospital, while protesters carried a
                 block-long banner with the word "Justice" repeated on it.

                 Martinez was removed from his post as mayor shortly after police violently broke
                 up a June 10, 1971 student march. He has said he was not responsible for the
                 deaths.

                 President Vicente Fox named a special prosecutor last year after the government's
                 National Human Rights Commission confirmed at least 275 "disappearances" in the
                 1970s and early 1980s. Fox, whose election ended the Institutional Revolutionary
                 Party's 71-year rule, has promised to end government-sponsored corruption and
                 violence.

                 Human rights groups charge that Mexico City's government, under the supervision
                 of the federal government, recruited, trained and paid a paramilitary group called the
                 "Falcons" to eliminate political activists.

                 Prosecutors had planned to question Martinez earlier this month, but the official's
                 deteriorating health forced them to delay the interview. On Monday, they asked him
                 who gave the orders the day of the massacre, but he refused to answer any
                 questions.

                 "He's in no condition to be talking," said Graciano Bortoni, who worked as interior
                 secretary when Martinez served as governor of Nuevo Leon state, where
                 Monterrey is located, from 1979-85.

                 Special government prosecutor Ignacio Carrillo later told reporters as he left the
                 hospital that Martinez's condition "is worrisome in such a way that one could not
                 insist a lot so as not to bother him, but still he handled it."

                 Speaking to reporters gathered outside the hospital, Bortoni blamed former
                 President Luis Echeverria for the 1971 blood bath, saying the police were under the
                 president's control.

                 Earlier this month, Carrillo questioned Echeverria to determine if there is enough
                 evidence to charge him with genocide and crimes against humanity.

                 The prosecutor has launched a formal investigation into complaints filed against the
                 80-year-old former president for the 1971 massacre and another in 1968.

                 Echeverria was interior secretary, a powerful position overseeing domestic
                 security, when Mexican troops ambushed mostly peaceful student protesters at
                 Mexico City's Tlatelolco Plaza in 1968. The government had said 24 people died,
                 but activists estimate about 300 people were killed.

                 When government paramilitaries killed more than 30 students during a 1971 protest
                 march, Echeverria was president.

                 Listening to the interview on Monday was Jesus Martin del Campo, whose
                 20-year-old younger brother was killed in the 1971 protest.

                 Del Campo said he was tired of excuses and wanted answers.

                 "They keep blaming each other so that they don't have to take responsibility, but we
                 know that they are both guilty," he said of Martinez and Echeverria.
