Stephen King apologized Friday for claiming that the conservative activist Charlie Kirk “advocated stoning gays.”

So when Mr. Kirk was shot and killed Wednesday at Utah Valley University, national attention turned, as it often has in tumultuous times, to the American university.

According to the affidavit, he entered the building from the southeast side, then, 13 minutes later, walked up a set of stairs to a walkway abutting the Losee Center.
