A Montgomery County Precinct 3 sergeant is under internal investigation after video captured him walking into a Woodlands family's garage uninvited while serving a civil court notice.

Sgt. David Weis entered the Frontera Circle home's garage on Monday, Aug. 24, after knocking three times at the front door, KPRC 2 first reported. Residents Christian and Masha Doyle emerged to find Weis standing inside. On camera, he said he stepped in to stand by a fan because of the heat.

"I just didn't want to pass out on your porch," Weis told the couple in the video.

When the Doyles referenced a posted "no trespass" sign, Weis said the sign did not apply to law enforcement and called the garage "open to the public" because the door was up.

Weis was there to serve a notice to appear for an eviction-related hearing. According to KPRC 2, paperwork shows the Doyles' landlord is seeking to evict them over one month of late rent and allegations of running an auto repair business from the home. The couple disputes both claims.

The Precinct 3 Constable's Office opened an internal investigation on Tuesday, Sept. 1, after receiving a complaint from the Doyles. Capt. Adam Acosta confirmed the probe to KPRC 2 on Thursday, Sept. 3. Acosta declined to say whether any policies were violated, citing the active investigation.

The office said in a written statement that it is reviewing the encounter, including the actions of everyone involved and all available documentation.

The Doyles have also filed complaints with the U.S. Department of Justice Civil Rights Division, the Texas Commission on Law Enforcement (TCOLE) and the Precinct 3 Constable's Office. They told KPRC 2 they began receiving calls from internal affairs investigators on Thursday, Sept. 3.

Civil rights attorney Courtney Vincent, who is not connected with the case, told KPRC 2 that a garage, especially an attached one, is considered "curtilage," or part of the protected property, and cannot be entered without a warrant or emergency circumstances. Whether the Doyles' garage is attached has not been confirmed. State records show Weis has been a licensed peace officer in Texas since 1977.

The Doyles said they want a public apology and retraining of the officer. No timeline for the investigation's completion has been announced.
