Updated March 7: Revised to include additional surveillance footage.

When a Carrollton couple woke up Thursday and discovered that their rainbow pride flag had been set on fire, they knew they'd been targeted.

"It was absolute hate, and they meant to do it," Markus Maguire told KXAS-TV (NBC5).

Maguire and his husband, Wilson Nash, have lived on Longwood Drive, near Parker Road and Plano Parkway, for about two years.

Around 8 a.m. Thursday, they found that the flag had been torn down from their home. It had been stuffed in their mailbox and — with mail from around the neighborhood used as kindling — set ablaze.

Damage to the flag was minimal because, police said, whoever started the fire closed the mailbox, cutting off the supply of oxygen to feed the flames.

Maguire said the couple had a replacement flag flying by noon — and, Nash added, "If they try to take it down again, we'll put another one up."

Jolene DeVito, a Carrollton police spokeswoman, told NBC5 that authorities have surveillance footage from neighbors that shows the crime and were seeking clearer footage.

The video appears to show a light-colored van pulling up to Maguire and Nash's home just before 3:30 a.m. Thursday. Someone gets out and takes the flag before leaving.

The vehicle returns after driving down the street several times, and then the fire is ignited.

In additional footage released Tuesday, the van is seen driving down a nearby street at 2:15 a.m. Police said it went down the street again at 3:24 a.m.

DeVito said that police are still investigating, but the flag-burning may be considered a hate crime. In addition, destroying mail is a federal crime punishable by up to three years in prison and a $250,000 fine.

Anyone with information about the incident is asked to call Carrollton police at 972-466-3578 or email crimetips@cityofcarrollton.com.

As for Maguire and Nash, they told NBC5 they had been overwhelmed by the support of their neighbors — many of whom are flying their own pride flags in solidarity.

"We feel the love," Maguire said.
