Man convicted and sentenced to life in 2015 family massacre
After just two days of testimony, jurors convicted David Conley on Thursday. He was accused of executing eight members of a family.

HOUSTON, Texas (KTRK) -- Houston jurors on Thursday have convicted David Conley, the man authorities say shot and killed eight members of a family, including six small children, execution-style in 2015.

Conley was then sentenced to life in prison without the possibility of parole.

The repeatedly delayed trial got underway Tuesday, with just two days' worth of testimony cross-examined in court. Closing arguments took place at the beginning of Thursday, with the jury receiving the case soon after by mid-morning.

Despite the trial's swift timing, testimony and evidence presented by prosecutors illustrated a grisly scene played out based on an alleged plan.

During the first day of testimony, Valerie Jackson's mother told the court she received social media messages from her daughter with "911" repeated before the killings took place on Aug. 8, 2015. Another message read "DVD has a gun," which Barbara Yankse, Jackson's mother, said meant David Conley has a gun.

On the second day of the trial, photos were presented to jurors, showing the victims' bodies being handcuffed and restrained throughout their northwest Harris County home. Conley was seen to have no reaction to the images being displayed.

Conley was on trial for the murders of the two adult victims - Valerie Jackson and her husband Dwayne Jackson.

The deceased children in the case are Nathaniel, 13; Honesty, 11; Dwayne Jr., 10; Caleb, 9; Trinity, 7; and Jonah, 6.

Conley wasn't facing the death penalty. Conley's defense team said he is intellectually disabled, and the U.S. Supreme Court has ruled death cannot be a punishment.
