A smartphone app meant the difference between life and death for one man.
On June 15, Sean Mcguire, 49, suffered a heart attack on Columbia Gateway Drive. He used the PulsePoint app to get help.
The app cuts the time someone is without help by notifying CPR trained people of an emergency nearby.
Maguire pulled out his phone and used the app. Simone Rockstroh was two buildings away and quickly came to his aid.
"I there I think within a minute, if not less than that of the time that I got the pulse point tone," Simone said. "So, those few minutes were critical, from what I understand Sean's ability to survive."
"She came over and assisted with the CPR until the first responders got there and I'm alive because of it," Maguire said.
Howard County was first jurisdiction in Maryland to use the life saving PulsePoint app.
