A Colleyville patrol officer remained in a neighborhood through the night as a precaution after an explosive device was found Sunday at a Colleyville home, police said Monday.
Colleyville Police Chief Steve Dye said at a press conference Monday morning that the device's components had been sent to a Bureau of Alcohol, Tobacco, Firearms and Explosive office in San Francisco in an attempt to determinue who made the triggering device.
Dye said it was an incendiary device intended to burn someone, rather than to explode.
Dye also released a 911 tape on which the woman can be heard saying, "I opened it and there was a battery in it. My neighbor said it looks like a homemade bomb."
Dye said there are no suspects.
"At this time, we still don't know how long that box had been there," said Colleyville Officer Raymon Cannon, the department's public information officer. "It's still too early in the investigation to say that the homeowner was the target or not."
The homeowner, a single parent who was home alone at the time, told police that she picked up a cardboard FedEx box at her house about 11 a.m. Sunday.
She told police that she didn't hear a truck and that no one had knocked on her door.
"It wasn't unusual for her to receive boxes at her home," Cannon said Monday. "She partially opened it and it looked suspicious. She called over a neighbor and the two of them decided to call 911."
When police arrived, officers also became suspicious and called a crew with the Northeast (Tarrant County) Explosive Response Team. Authorities also evacuated homes on the cul-de-sac.
The explosives team used a remote-operated vehicle and a water cannon to render the device safe while it was on a sidewalk, police said.
No one was injured.
Cannon said that authorities determined that the device was explosive or could incinerate, but no other details were released.
Components of the device were being analyzed by ATF officials.
