A phone number that Bexar County sheriff’s detectives said Roderick Dotson Jr. gave to his alleged victim is what led to his arrest in a rape case, according to an arrest warrant affidavit.
Dotson was taken into custody Thursday on a charge of sexual assault of a child.
The affidavit stated that a 14-year-old girl told investigators she was sexually assaulted Tuesday afternoon by a man whom she met outside a Dollar General store in Northeast Bexar County.
The girl said she was walking past the store on Walzem Road near Tarrasa when the man identified himself as “Rob” and told her he was 16 years old, the affidavit stated.
She told investigators that at some point after she told him she was only 14, he grabbed her by her hair and dragged her to a fence line in a field behind some nearby homes and sexually assaulted her.
"We never have that kind of problem here. Never,” said Ricardo Avalos, a former police officer who lives in the neighborhood “I mean, this is the first time we heard something like that."
Avalos, however, said he did see the commotion Tuesday when detectives began their investigation.
He said deputies swarmed the grassy area across the street from his home and appeared to be looking for evidence.
“They were coming from over there. There were cops over there,” Avalos said, pointing and attempting to re-create the scene.
This type of crime, he said, is unusual for his neighborhood.
Perhaps, even stranger, though, is what investigators said the suspect did next — gave the alleged victim his phone number.
The affidavit stated that the girl told detectives her attacker ordered her to grab a pen and paper so he could write it down for her.
The phone number, investigators said, proved to be an important clue.
They said they did some research and discovered that Dotson had called the same number during a prior stay in jail.
He was booked back into the Bexar County jail Thursday with bond set at $75,000.
