UPDATE: Pinellas County Schools officials said James Seevakumaran graduated from Seminole High School in 2001. They added that he also attended Seminole Elementary School and Seminole Middle School.
Seminole, Florida -- Students arriving at Seminole High School on Tuesday will hear about a former student at the center of a nightmare that was narrowly avoided.
We've learned James Seevakumaran had been a student at Seminole High School before studying business at the University of Central Florida.

He also spent time in a neighborhood in the City of Seminole. 10 News spoke with people in that community.
While no one was willing to talk with us on camera, one neighbor did tell us Seevakumaran was "weird." Others said he was "quiet."
Police in Orlando say Seevakumaran had gathered four explosive devices, a pair of guns, and hundreds of rounds of ammunition.
He had drawn up a plan to launch a Virginia Tech-style rampage from his dorm at UCF, where he had stopped paying his bills and was about to be evicted.

"We found some notes and some writing that indicated this was a planned attack," UCF Police Chief Richard Beary said.
"This individual had laid out a timeline, and laid out some of what we feel were going to be his actions."
But officers say it looks like he wasn't ready for a quick police response to his first steps.
He pulled the fire alarm early Monday morning -- police think he did it to get everyone out in the open -- and then pointed a gun at a roommate.
That roommate ran, hid in a bathroom, and called 911.
Within minutes of those warning signs early Monday, officers were arriving at the dorm,and the 30-year old student shot himself.
According to UCF, Seevakumaran was in the process of being evicted from his room for not paying his university fees.
Freshman Winston Lightbody heard the commotion inside the dorm and was evacuated with 500 other students, stunned by what cops found.
"You never know who has bombs or who has guns," Lightbody said.
"It could have been a very bad day for everyone here. All things considered, I think we were very blessed here at the University of Central Florida," Chief Beary said.
