Las Vegas police say there may be more victims in a string of slayings of Las Vegas prostitutes whose bodies were found along highways.

Police Detective Larry Hanna is asking police in other areas to check for cases similar to those of four young women with ties to Las Vegas.

The body parts of three of the women have been found off of highways in Las Vegas, California and Illinois, and a fourth woman who matches the descriptions of the others is missing.

Hanna say the women could have been slain by the same person, possibly a truck driver because of the proximity of the women to major highways.

The victims were white women between the ages of 19 to 25 and worked as prostitutes. They disappeared between 2003 and 2006.

Hanna says no suspects have been named.
