A 77-year-old man suffered life-threatening wounds after he was shot in a robbery in the Mission on Friday evening.

According to police, four men with guns entered a building on the 2300 block of Mission Street between 19th and 20th streets around 5:20pm. Once inside, one of the suspects shot the victim and targeted two other men, one 60 and the other 63, before leaving.

Police have not released a detailed description of the suspects or identified any items that may have been stolen. The victim was transported to a hospital to be treated for his injuries, but there's no word on his condition.
