The July 3 account, reviewed by Hearst Newspapers, discloses several previously unreported incidents the trooper witnessed in Eagle Pass, where the state of Texas has strung miles of razor wire and deployed a wall of buoys in the Rio Grande.

According to the email, a pregnant woman having a miscarriage was found late last month caught in the wire, doubled over in pain. A four-year-old girl passed out from heat exhaustion after she tried to go through it and was pushed back by Texas National Guard soldiers. A teenager broke his leg trying to navigate the water around the wire and had to be carried by his father.

The email, which the trooper sent to a superior, suggests that Texas has set “traps” of razor wire-wrapped barrels in parts of the river with high water and low visibility. And it says the wire has increased the risk of drownings by forcing migrants into deeper stretches of the river.
