Law enforcement and prosecutors are learning from technology professionals on how to better track suspects who prey on children using their devices.
Irish Burch is President and CEO of the Dallas Children's Advocacy Center which puts on the annual Crimes Against Children Conference going on this week in Downtown Dallas.
"As a forensic interviewer, ask children specific questions as to what was happening at this point in time," Burch said.
"They can look at their heart rate on their Apple Watch and different things or locations to see that that would line up with what that child was saying."
She says the training is necessary with how predators are getting better at using technology and social media to go after children.
"Perpetrators are identifying more and more ways through technology to victimize the children," she said. "If there are any levels of expertise, subject-matter experts, they are at this conference."
All 50 states and 20 countries are represented at the conference going on through Friday.
Since the conference began 37 years ago, it has trained over 92,000 professionals from all 50 states and several countries.
