Come on, folks, This isn't rocket science. The motive is pretty clear. It's a classic child-custody related familicide. It's all about abuse and control.
Dad is identified as JONATHAN COMANCHO.

PORT LAVACA — Investigators say deputies were twice called to a South Texas home on child custody issues the night before a woman and her three young children were found dead inside, but a motive behind the killings remains unclear.
Jonathan Camacho remained jailed Friday on a murder charge in the death of his 23-year-old wife, Dulce Cumpean-Camacho, and capital murder charges in the deaths of the three children: 4-year-old son Zavier Camacho, 1-year-old Sierra Camacho and 3-month-old Faith Camacho.
Calhoun County Sheriff George Aleman said deputies were twice summoned Sunday night to a home in Port Lavaca on child custody issues, The Victoria Advocate reported. But early Monday, firefighters were called to a fire at a one-room shed where the family lived. The four bodies were found in the debris.
“Initial reports from family members were that people were inside the residence,” the sheriff’s office said in a statement.
Deputies, assisted by Texas Rangers, later determined the deaths were homicides. Preliminary results from autopsies determined that the victims were stabbed, according to a statement released Thursday.
The home was on a compound where other relatives also lived.
“We knew (Jonathan) loved them. If we would have thought they weren’t safe, we would have made him leave,” said Yesica Cumpean, 25, the slain woman’s sister.
An arrest warrant was sealed by a judge for 30 days at the request of law enforcement, the newspaper reported.
