Authorities said Tuesday that a man who attacked rapper Tory Lanez in a California prison is an inmate serving a life sentence for second-degree murder who was previously convicted for an in-prison assault with a deadly weapon.

Lanez was hospitalized after an attack Monday at a California prison where he's serving a 10-year sentence for shooting hip-hop star Megan Thee Stallion in the feet, authorities said.

What began as a festive campaign march quickly turned into a scene of terror in the Mexican state of Veracruz on Sunday night when a mayoral candidate was gunned down alongside three other people.
