A man charged in the deaths of a couple and six children at a Houston home has professed love for one of the victims — his son — and says he thought the children were "growing up to be monsters."

David Conley was being held without bond Wednesday on capital murder counts. Authorities say Conley formerly was in a relationship with the children's mother, Valerie Jackson, and one boy was Conley's son.

Conley gave jailhouse interviews to several Houston television stations, saying the children had been disrespectful to him and weren't being raised properly. He also said Jackson's husband was harassing him, and previous charges of domestic violence against him were "all lies."

He's next scheduled for court Sept. 15. Authorities haven't decided whether to seek the death penalty.
