^ This happened a few miles west of our neighborhood and a couple of the schools in our district were on lockdown (they're much closer to that particular synagogue than our elementary and high school are). My friend lives over that way and he said he was hearing tons of sirens and helicopters overhead before the alerts started hitting phones and the news he figured something was up but didn't know what/where things were happening.
IIRC, Temple Israel is the largest synagogue in Michigan in terms of membership, and one of the largest in the country. It's facility is pretty extensive with a school and an early childhood center, meeting spaces, etc. We've been there for a bat mitzvah and a bar mitzvah and are close friends with a few families that go there regularly. I'm glad to hear that it sounds like the shooter was the only casualty.
Temple Beth El is much closer to our house and we know a lot of families that go there.
They had a similar incident back in 2022 that also, thankfully, did not turn out as bad as it could have been. Ever since that incident they now have a round the clock security checkpoints to get on to their property. On a less somber note, The current home of Temple Beth El was designed by noted architect
Minoru Yamasaki and it's truly a striking building inside and out.
One final note on the active shooter at the temple... My wife and I were both at home at the time of the incident and a little afterwards her cell phone got an automated emergency alert telling her to shelter in place but I did not get one. I wonder how that happens?
