Internet Used to Find Man Who Is Charged in 2 of 10 Killings

A search by Illinois State Police of Internet mapping companies led to an exact match between features on a map sent to the Post-Dispatch and one found on Expedia.com.

On June 3, the Microsoft Corporation, which tracks access to that Web site, showed the F.B.I. that only someone with the Internet Provider address 65.227.106.78 visited the Expedia.com site and searched the West Alton area within days of the map's mailing to the Post-Dispatch. The user name of that IP address was ''MSN/maurytravis.''

The police have said they believe an 11th woman, who survived an attack and was found near death in April 2001 in East St. Louis, was one of the killer's intended victims. That woman, 44, suffered brain damage, is in a nursing home and has been unable to help investigators.

In 1989, Mr. Travis was sentenced to a 15-year prison term for armed robbery. He was paroled in June 1994, a State Department of Corrections spokesman, Tim Kniest, said. In January 1998 he pleaded guilty in St. Louis to possession of drugs and was sentenced to two years of probation. He later spent nearly a year in a state drug treatment program.

Last November, Mr. Travis was returned to the treatment program after being arrested for misdemeanor assault, Mr. Kniest said.

Mr. Travis was released in March and remains under parole supervision, Mr. Kniest said.
