SAN CLEMENTE, Calif. AP – A Houston-area attorney involved in a bitter custody dispute was found fatally shot along with her two young daughters and mother in an apparent murder-suicide after she was ordered to bring the children to a court hearing, authorities said Tuesday.

Investigators found 38-year-old Elizabeth Fontaine’s body next to those of her mother, 67-year-old Bonnie Hoult, and two children Monday at an upscale Orange County home. Forensic tests will be needed to determine who pulled the trigger because a handgun was found between the two women, sheriff’s spokesman Jim Amormino said.
