A Texas woman accused of gunning down her estranged husband and his daughter has an eerie message about making "room for better people" posted on her Facebook page, the Fort Worth Star-Telegram reported.

Veronica Dunnachie, a known supporter for gun ownership rights, was arrested Wednesday after the bodies of Russ Dunnachie, 50, and Kimberly Dunnachie, 20, were found in an Arlington home by police conducting a welfare check, according to a search warrant affidavit obtained by the newspaper.  

The 35-year-old suspect also drove herself to a mental hospital after allegedly shooting the father and daughter.

Those who knew the Dunnachies said the couple was in the process of getting a divorce after being married since 2006. Both husband and wife had temporary restraining orders against each other and were granted joint custody of the four children, the newspaper reported. Veronica Dunnachie was also ordered to vacate the Edinburgh Street home by the end of December.  

Russ' divorce attorney, Alison Porterfield, said he showed interest in working out their differences but Veronica never showed up to counseling.

"Sometimes removing some people out of your life makes room for better people," reads a quote from Veronica's Facebook page. Pictures on the account show her posing with an assault rifle and other weapons. She was also known to attend Open Carry activities.

Police said one of Veronica's friends received a call from her after the shootings. Guy Potter said Veronica sounded distraught and said "she couldn't be helped this time as she had just shot her husband" and his daughter, according to the affidavit.

Potter told Veronica to go to a nearby mental facility and then called another friend, who then called police, the Star-Telegram reported. Potter said he was too upset with what Veronica told him to call 911.

As Veronica was held at the Arlington Jail Thursday without bond, neighbors were grappling with how the divorce took such a gruesome turn.

"I never thought it would come to this point. I just knew they were having problems," Cara Vannatta, a neighbor who used to babysit for the Dunnachies, told NBC DFW.
