Sexual assaults happened near home of 17-year-old suspect, records show

Two elderly women have been beaten in recent weeks. The teenager arrested for them should be tried as an adult.

SAN ANTONIO — A 17-year-old is set to stand trial as an adult after being charged with two attempted aggravated sexual assaults and then jailed.

Newly released court documents paint a detailed picture of the evidence police have gathered as part of their investigation into Justyn Antron Curl, according to the suspect police responsible for both attacks.

Both attacks occurred in a small geographic area in northwest San Antonio, and both scenes are near Curl’s home.

Police said one of the victims was in his 60s and the other in his 60s.

Court records say the first attack happened on Bandera Road in Loop 1604 in late June. A woman told police she was sitting in her vehicle when a man asked her to drive her. The victim said that when she refused, the man opened the passenger door and got into his car.

The woman said the suspect then pulled out a knife and threatened to stab her if she did not perform a sexual act.

The victim said that as she fought back, the man punched her several times in the head and then tried to pull her clothes off. She told authorities she fought long enough for the man to give up and flee, taking his cellphone with him. At that time, she ran to a nearby business to call the police.

In Curl’s arrest affidavit, police wrote that they recovered a very distinctive “Slitzer Rostfrei” stainless steel knife from outside the car. A technician for the evidence was also able to take fingerprints from the door handle of the vehicle.

Days later, the affidavit details that the printout matched evidence the police already had in their files regarding another case.

Regarding the previous case, the affidavit explains that Curl was to be under house arrest at his home, about a mile away. He was also supposed to wear a GPS monitor.

The detective wrote that he contacted the company tracking the device and was told that, at the time of the assault, the suspect’s device had not been detected in the home.

The affidavit goes on to state that the detective “has learned that it is possible to prevent these types of devices from tracking GPS coordinates for long periods of time by wrapping the device with a masking agent such as foil. strong aluminum”.

With fingerprints and GPS data, detectives obtained and executed a search warrant at Curl’s home. Among the items recovered were the victim’s cell phone and a Slitzer Rostfrei knife from the kitchen.

Regarding the attack on the second victim in early July, the initial offense report indicates that the victim, who is 70, was out for an early morning walk. The affidavit says there is surveillance video of a man wearing a distinctive “SpongeBob Squarepants” hoodie following the woman as she approached Bowens Crossing.

The woman told police her attacker demanded a sex act. When she refused, the man allegedly dragged her into a nearby drainage ditch and began punching her in the face with a clenched fist. The affidavit goes on to say that the suspect threatened to shoot the woman if she did not comply with his demands, and also hit her on the back of the head with a piece of concrete.

The woman said the man tried to undress her but she fought back until he gave up and ran off with his cellphone.

The affidavit says that when they were searching Curl’s home, they found the hoodie seen in the surveillance video and a tracking device traced the victim’s phone to within a few feet of Curl’s home.

San Antonio police recently released Curl’s photo and are asking anyone who may know of other crimes to come forward. Neighbors in the area said details of the chilling attacks had been circulating on the Nextdoor app for weeks.

Curl remains jailed on bonds totaling $150,000 on the most recent charges.

Prosecutors were unable to answer questions related to why Curl was under house arrest and under a court order to wear a GPS tracking monitor.

Police are asking anyone with information about these or other cases to come forward.
