Mango, a 3-year-old Maltese, got out during a Princeton warrant service and was killed by a car.

PRINCETON, Texas — Update, Aug. 17, 2026: The Collin County Sheriff’s Office told WFAA that deputies did not open the gate at the neighboring home and that the dog was already loose before deputies began surveillance. “The only property deputies entered was the residence where the warrant was served,” Sgt. Jessica Pond, the agency’s public information officer, wrote in an email.

Raider likes to run.

“I love him,” Hallie Larson said. “He’s my best friend. He’s so sweet.”

It’s why she keeps a padlock on her backyard gate. And it’s why she feels for her neighbor two doors down.

Collin County sheriff’s deputies swarmed the block Friday to make an arrest at the house in between them. The neighbor two doors down said on social media that deputies opened her backyard gate to reach the other property, and that her 3-year-old Maltese, Mango, ran away.

“There’s officers everywhere, and yeah, she was very frantic about it,” Larson said.

Later, Mango’s owner shared an update. Mango had been hit by a car and died.

Now, the sheriff’s office is offering condolences and part of an explanation.

In a statement, the Collin County Sheriff’s Office said deputies served a felony arrest warrant for sexual assault of a child in Princeton on Aug. 14, at the request of the Princeton Police Department. Deputies took Issac Harris into custody on the warrant. Trevon Harrison was also arrested at the scene for interference with public duties after, according to the statement, he tried to interfere with deputies as Harris was taken into custody.

Before serving the warrant, the statement said, deputies surveilled the residence and the surrounding area for roughly 30 to 40 minutes. During that time, they saw a small white dog loose in the neighborhood.

“The dog belonged to a neighboring residence and was observed prior to deputies approaching or entering the house where the warrant was served,” the statement said.

Deputies also saw people searching for the dog, according to the statement, and told them the direction they had last seen it running. The sheriff’s office said it learned later, through social media posts, that the dog had been struck and killed by a vehicle.

“We understand that the loss of a precious family pet is traumatic and very difficult,” the statement said. “We wish to convey our condolences to the dog’s owner and family over the loss of their little companion.”

The statement did not say whether deputies opened the gate.

In her post, Mango’s owner attributed the actions to the Princeton Police Department. The department, in a social media post of its own that went up before the sheriff’s office released its statement, said it had no role in the operation.

“Although the incident occurred within the City of Princeton, the Princeton Police Department was not notified in advance that the warrant would be served, was not present during the execution of the warrant, and did not respond to the scene,” the post said.

The department said questions about the planning, service and execution of the warrant should go to the Sheriff’s Office. The Sheriff’s Office, in turn, said it served the warrant at the Princeton Police Department’s request.

To Larson, her neighbor’s account is plausible. It is also troubling.

“Their gate is never open, as far as we see when we drive past,” she said.

“I understand the officers have a job that they need to do, and I completely respect that, and I appreciate that of them,” Larson said. “But you do have to take care of people’s property, especially a loved pet.”

Because if Mango was anything like Raider, she was more than a pet.

“Yeah, it would be really devastating if something happened to him,” Larson said.

For Mango’s family, that is exactly what happened. And they still want answers.

WFAA attempted to reach Mango’s owner and was unsuccessful.
