Kansas City, Mo. ? Police announced Tuesday they were investigating a possible link between a body found in an alley and the slayings of six women whose remains were found on vacant property in an inner city neighborhood more than two miles away.

Terry Blair, who spent 21 years behind bars for killing his pregnant ex-girlfriend, has been charged with killing Sheliah McKinzie, 38, one of the six women whose bodies were found in an 18-block area east of downtown.

Police believe the six slayings are the work of the same killer and have asked prosecutors to charge Blair, 43, with the other five killings as well as in three assault and rape cases.

Police were led to the latest body by a man they talked to Monday.

The body was mostly skeletal and too badly decomposed to determine the sex or race.

Lockhart said police were looking into the possibility that the killing was linked to the other six because the latest victim — like the others — was found near vacant property and was covered. The alley where the body was found was so filled with debris that police had to use a small earth mover to remove tree limbs and leaves.

Blair was paroled seven months ago, four years shy of serving his full 25-year sentence for killing his ex-girlfriend, Angela Monroe, whom he was angry with because she was working as a prostitute.
