Alfonseca, who is accused of robbing TowneBank at Virginia Beach Town Center, posted pictures and video on his Instagram account showing the note he gave to a teller at the branch Monday, as well as the teller piling money on the counter.
He maintained he simply and politely made a request, and the teller obliged him.
The note read:
"No threats in it. If you see me in the video or whatever like that, I have a shirt on -- no weapon, no mask -- and she passes me the money," said Alfonseca. "I don't want to get her in trouble. Maybe she made a mistake. Maybe she made a mistake, and I didn't make a mistake."
Alfonseca, who drifted off topic several times during the interview, said he hoped by posting the items to Instagram, he would get the attention of certain people, some of whom had stolen ideas from him during the course of several years. Exactly what he hoped to accomplish once he had their attention, he wouldn't specify.
Alfonseca said he left the bank with a bag of money. Within half an hour, Virginia Beach police officers found him and arrested him.
"'Get down! Get down in the dirt!'" Alfonseca recalled were one officer's words to him. "I was like, 'All right. Cool.' So, I got down."
Alfonseca added, "For real, I felt like I got robbed, 'cause they gave me the money. Then, the police robbed my brain," he stated.
Alfonseca is being held without bond for the time being. He is supposed to have a preliminary hearing June 12.
As far as the crime for which he is charged, Alfonseca said, "Everything is relative, you know what I mean? It's however you want to take it. I'm telling you why I did what I did, you know what I mean? But if justice is served in that thing, then I think justice shall be served all around."
