MANILA - Before she was stabbed to death in an apparent case of robbery, Assistant Special Prosecutor Madonna Joy Ednaco-Tanyag attended to her duties at the Sandiganbayan 3rd Division last Monday, according to court employees.

Five-month pregnant Tanyag had three scheduled hearings at the anti-graft court all scheduled at 8:30 a.m. before she went to Visayas Avenue in Quezon City, where she was killed.

Her first hearing was the travel motion of Ruby Tuason, one of the accused in the multiple graft and malversation of public funds cases in connection with the use of Malampaya funds involving former Arroyo cabinet secretaries Rolando Andaya Jr. and Nasser Pangandaman, and businesswoman Janet Lim Napoles.

She also tackled the travel motion of former Iloilo Rep. Judy Syjuco, who is facing graft and malversation of public funds cases.

Her last hearing, the trial of former Norala, South Cotabato Mayor Romeo Januto, was called but was cancelled.

Among hardworking employees of the Office of the Ombudsman, Tanyag also handled other high-profile cases such as that of former Vice President Jejomar Binay, former Makati City Mayor Junjun Binay, former Davao Del Sur Rep. Marc Douglas Cagas, Cagayan De Oro City Mayor Oscar Moreno, and former Caloocan City Mayor Enrico Echiverri.

Police arrested the primary suspect in Tanyag's killing late Monday.
