"Weird just means he stands out from the normality. He was a normal person but his mentality was different," Former High School Classmate Alhon Carrenca.
18 year-old Vladislav Miftakhov lived in San Carlos, California for years and graduated from a Northern California high school last June.
His former classmates say even though he was different, the person they knew wasn't violent.
"He's like genuinely a kind person I don't think he would try to hurt anyone I think he was just intrigued with the chemistry and it let him down the drain you know," Carrenca says.
Altoona Police discovered the materials in a brief case Friday after searching for and finding drugs in the 18 year olds apartment.
“Once they opened the brief case, it became immediately apparent to him that there were two for lack of a better word, bombs and assorted bomb making materials. Which were contained in the brief case,” Lt. Jeffrey Pratt of the Altoona Police Department says.
The FBI officially took over the investigation Monday.
Because Miftakhov is a Russian national, Altoona Police Lieutenant Jeffrey Pratt says there's a lot more questions.
“This may not be somebody who is just tinkering with explosives. That is not necessarily a normal human endeavor, and the FBI in addition to being a law enforcement agency, they are concerned with possible terrorist implications or what not,” Lt. Pratt says.
WTAJ reached out to Miftakhov's mother in California, but messages were not returned. Miftakhov remains in the Blair County Prison and we're told at this time he has yet to hire an attorney.
