Rex Heuermann, the architect convicted in the killings of eight women, was sentenced Wednesday to multiple terms of life in prison without the possibility of parole.

Heuermann, 62, admitted in April to strangling eight women and leaving their remains in remote areas of Long Island between 1993 and 2010, which have been dubbed the Gilgo Beach killings. The plea deal carried a guaranteed sentence of three consecutive life terms, which were imposed in a Riverhead, New York, courthouse.
