Houston Police are looking at possible links between the slaying of a Waco, Texas, businessman two years ago and the June slayings of four former members of a polygamous sect, Leon County Sheriff Royce Wilson says.

Police in Houston and Irving have said the four slayings may be linked to the Church of the Lamb of God, a violent sect that reportedly believes in killing members who leave the group, Wilson said Saturday.Three of the four victims of the June slayings were former members of the radical polygamous cult, which has Utah ties. The fourth victim was the daughter of one of the three men.

Wilson said Houston investigators told him this week the same people may also be responsible for the October 1986 slaying of polygamist Harold "Jack" McCollum, a Waco tire dealer.

McCollum was found dead along the banks of the Navasota River in Leon County. McCollum was last seen in a Dallas parking lot getting into a dark-colored pickup with two men.

Texas authorities have questioned five members of the religious sect who are jailed in Phoenix on auto theft charges. But thus far no charges have been filed in the Texas slayings.

Two of the five Arizona suspects are sons of Ervil LeBaron, a founder of the Church of the Lamb of God. LeBaron died in the Utah State Prison in 1981 while serving a life sentence for the murder of rival polygamous leader Rulon Allred in the Salt Lake area.
