The dive team responded to the 7100 block of Avalon Bend Circle in the Lakes of Avalon Village subdivision in north Harris County, where a suspected drunk driver said she couldn't remember if her boyfriend was in the car underwater, Sheriff Ed Gonzalez said.
According to authorities, the driver said her boyfriend may have been inside the vehicle when it went under.
Meanwhile, she was arrested, accused of driving while intoxicated.
Shortly before 9:30 a.m., authorities told ABC13 there was no body in vehicle.
In an update from Precinct 4, ABC13 has learned there may not have been a man in there with her at all.
Hours earlier, at about 3:55 a.m., the woman knocked on a resident's door, frantically saying that she had been in a crash, Precinct 4 said.
It turns out the woman entered the neighborhood, blew through the stop sign, and crashed into the pond, according to officials.
Precinct 4 says that when first responders tried to talk to her, she wasn't really able to give them details. Still, they determined she was impaired after a field sobriety test.
Authorities said the woman told them various stories, including that "one of her boyfriends" may have been with her.
Officials confirmed she was coming from a party, but couldn't determine who she was with. That's when Precinct 4 contacted the sheriff's office, whose dive team responded to the scene.
No one was dead inside the vehicle or the pond.
The woman was arrested on suspicion of driving while intoxicated and booked into the Harris County Jail.
The crash happens just a day after a body was found in a separate lake in the neighborhood, but officials say the two incidents are unrelated.
A man's body was found in the same neighborhood in the water in the 7200 block of Avalon Bluff Drive, said the Harris County Constable Precinct 4's Office, who responded to the initial call the day before.
Investigators said the man's body was discovered by neighbors walking Thursday morning.
The Harris County Sheriff's Office said the victim was potentially a resident of the neighborhood.
Sgt. Sidney Miller said investigators were speaking with neighbors and checking for surveillance video to see how and when he might have ended up in the water.
Miller said deputies believe the man was possibly reported missing on Monday but haven't confirmed his identity.
Officials did not elaborate if the man had suffered any trauma or had visible injuries.
