An X account that appears to have belonged to the deceased suspect has violent anti-LGBTQ messages dating to 2018.

The 27-year-old man who police say shot and killed a California business owner over a Pride flag draped in her store appears to have had a yearslong history of posting disturbing — and often violent — anti-LGBTQ messages on social media.

The suspect, Travis Ikeguchi, gunned down Laura Ann Carleton, 66, on Friday, after confronting her and “yelling many homophobic slurs” over her clothing store’s Pride flag, San Bernardino County Sheriff Shannon Dicus said at a news conference Monday. Shortly after fleeing the store, Mag.Pi, Ikeguchi was killed in a shootout with law enforcement.
