Houston_Rusty Yates, whose first wife drowned their five children, has started a new family.
Yates said Monday that his second wife, Laura, gave birth to a son March 20.
"He's doing well," Yates said, declining to disclose the child's name. "I'm happy."
The couple wed in March 2006, a year after he divorced his first wife, Andrea, who is in a state mental institution.
Andrea Yates drowned the couple's five children - ages 6 months to 7 years - in June 2001 at the family's home near NASA's Johnson Space Center, where Yates works as an engineer. She said she was trying to save them from the devil; she was convicted of capital murder and sentenced to life in prison in 2002.
But an appeals court in 2005 overturned her conviction because of erroneous testimony. Andrea Yates was then found innocent by reason of insanity in July 2006 and sent to the institution.
"She's at peace with it," George Parnham, Andrea Yates' lawyer, said. "She obviously wants Rusty to carry on. ... She wants only the best for Rusty's new family."
Parnham said he sees Yates frequently and described her as "doing well."
"She's adapted so well to the realization that she has a mental illness and that she has to take her medication," he said.© 2008 The Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.
