Police say responding officers arrived to find a man and a woman lying next to each other in the street suffering from multiple gunshot wounds. According to police, the 55-year-old man was shot three times in his abdomen and his 43-year-old fiancé was shot nine times in her abdomen, legs and feet.

“It appears that our shooter was in very close proximity, ” said Chief Inspector Scott Small. “The ballistic evidence is just several feet away from where both of these victims were laying side by side on the street, so we know that the shooter fired these shots from point-blank range.”

Both victims were rushed to Aria Torresdale Hospital in critical condition.

Authorities believe the shooter fled on foot to a home along the 6100 block of Algon Avenue. Police searched the area and found a semi-automatic gun which they say appears to be the weapon used in the shooting.
