Reporter: "Texas equusearch was out with their sonar boat, scanning the bottom of the river for her body. They are the ones who found her body, correct?"
Sheriff: "No, I'm not gonna say who exactly or what agency discovered her body today. I will say this- due to the lowering we were able to contact TRA, trinity river authority, they slowed down the outflow from the reservoir and it allowed the water to go down and her body was discovered there in the water. I'm not going to say whether it was Harris County, or Montgomery County, or Equusearch, it was a conglomeration of a lot of love and law enforcement networking together.."

So although he started his answer with "no" it didn't seem clear that equusearch WASN'T involved in finding her. Just that multiple agencies had a hand in it. It could be that TES saw something on SONAR where they were lowering the water, but someone from another agency was first to spot her body under the water, someone else confirmed it, someone else retrieved her. We just don't know. imo
