Prosecutors say in November and December, Keller targeted one victim because that person was Jewish and another because Keller thought that person was gay.
It’s unclear, however, why others were targeted.
“He shot a gun into establishments and residences throughout the county. He vandalized cars and posted extremely disturbing messages on Instagram,” Suffolk County District Attorney Timothy Sini said.
“This may have gone back and forth both ways. I think there’s a lot more to this case than we heard today,” said Glenn Obedin, Keller’s attorney.
No one was hurt in the shootings.
Keller faces up to seven years in prison if he’s convicted.
