HARRIS COUNTY, Texas (KTRK) — The Harris County Sheriff’s Office is investigating an apparent double murder-suicide in northeast Harris County where three people, including two brothers, were shot and killed during what officials are calling a domestic dispute among neighbors Thursday evening.

Officials said it started in the 11700 block of S. Spicewood Lane around 11 p.m. when a woman and her boyfriend were fighting.

HCSO said during the argument that the woman took her two children to the home next door where three brothers lived for safety reasons. Police said they were unclear about how well the men knew the woman but were told that the woman felt safe enough to go there for help.

The woman’s boyfriend then came over, where he was confronted by the three brothers outside. Police said that is when the boyfriend reportedly pulled out a gun and fatally struck 2 of them.

HCSO said one of the three brothers also pulled out a weapon and returned fire at the suspect, who ran back to the home where he shared with the woman.

HCSO said that shortly after, the woman’s boyfriend then turned the gun on himself once deputies arrived. He was pronounced dead at the scene.

Investigators said the two brothers who were killed were in their 30s and 50s.

While looking at the scene, deputies said this was not the first time law enforcement was called to this home. Officials said just a few days earlier, there had been a family violence call between the woman and the boyfriend, but details on the incident were limited.

No names have been released of the victims, and officials said the surviving brother, the woman, and her two kids are said to be OK and are cooperating with law enforcement.

Robert Roberson, the first person in the U.S. set to be executed based on the controversial “shaken baby syndrome” hypothesis, has been granted a temporary reprieve. Late Thursday, the Texas Supreme Court issued a stay, delaying his execution and capping a series of legal maneuvers. Roberson, convicted of murdering his 2-year-old daughter, expressed shock and gratitude upon learning of the delay, proclaiming his innocence.

His legal team, led by attorney Gretchen Sween, lauded bipartisan Texas lawmakers for intervening to allow Roberson to testify in an upcoming legislative hearing focused on “junk science” used in legal cases. Roberson’s conviction was largely based on medical testimony supporting “shaken baby syndrome,” a diagnosis now widely questioned by experts.

New evidence suggests that Roberson’s daughter had pneumonia at the time of her death, which could have led to her fatal condition. Over 30 medical experts and a bipartisan group of Texas lawmakers have urged a review of Roberson’s case, arguing that the new scientific evidence warrants a new trial. Roberson’s execution, initially set for Thursday, was put back on track briefly before the Texas Supreme Court intervened. A legislative hearing, where Roberson is set to testify, is scheduled for Monday.
