DETROIT -- A 15-year-old Detroit girl was killed and another critically wounded in a drive-by shooting early Monday morning on Detroit's northwest side.

According to police, three girls, all 15, had flagged down a car occupied by a 34-year-old man and a 16-year-old youth at around 4:30 a.m. near the intersection of Fenkell Street and Wyoming Street.

One of the teens told Local 4 they were getting a ride to a nearby store, but they ended up driving around for a while.

At some point, a black vehicle pulled up in front of them and started shooting, killing Martha Barnett, police said.

"I don't even think they even knew what they did to Martha," said survivor Tiffany Whatley "She's shot. They were just shooting for nothing."

Whatley said she tried to revive her friend, crying, "Martha, Martha, wake up, wake up, say something, say something. And she was dead. Blood was all on the side of her face."

The 16-year-old in the car was also injured with a bullet wound in his hand.

The driver rushed them all to the hospital, with Barnett dead and another girl, Dominique, shot in the shoulder.

"She was just at the wrong place at the wrong time," said Melissa Barnett, Martha's sister. "Nothing I can say, really, except that I miss her."

"The only thing the family's doing now is just hoping and praying that we can find the (shooter) before he does this to someone else," said Thomas Barnett, the victim's uncle.
