John Ray chimes in.
Rex Heuermann, who is accused of murdering seven women, is expected to plead guilty April 8, a source familiar with the matter said.

"John Ray, an attorney for Valerie Mack's son, said that his client was "cautiously awaiting the facts." Ray added that if a deal is struck, much will depend on the information presented during a potential allocution.
"If the full facts do not come out, make no mistake, we are going to pursue this," he said. "It's not over."
Ray added that his client wants authorities to investigate Heuermann's wife and children, who have not been criminally charged with any wrongdoing.
A lawyer representing Heuermann's wife, Asa Ellerup, did not immediately return a request for comment.'
