French PresidentNicolas Sarkozyhas vowed toinvestigate the case of aFrench-Canadian journalist who went missing in Ivory Coast more than three years ago.

Sarkozy met with the family of reporter Guy-André Kieffer in Paris on Thursday and promised efforts would be made to find out what happened to Kieffer, who is believed to be dead.

Kieffer's wife, Osange Silou-Kieffer, said she was pleased with the meeting.

"He told us very clearly of his determination, and the determination of French political authorities, to help us in the case, which wasn't the case before," she said.

She said former president Jacques Chirac, who left office in May, never answered her requests for a meeting.

Kieffer, a father oftwo who holds French and Canadian citizenship, was last seen in a shopping mall in Abidjan, the capital of Ivory Coast, on April 16, 2004.

Hehad been working as an independent journalist in the country for several years, writing articles about corruption for several publications. Prior to his independent work, he worked from 1984 to 2002 as a journalist with the French economic newspaper La Tribune.

He was 54 when he disappeared.

His wife said French judges would like to question certain people in the Ivory Coast about the case, but have not been given the access. She asked Sarkozy to push Ivory CoastPresident Laurent Gbagbo to grant that access.

One of the people being investigated in the case is Michel Legré, a brother-in-law of Gbagbo's wife.
