Mourners gathered at a Saskatoon church Saturday for the funeral of 17-year-old Sarah Wensley, five days after she and another teen were killed in a horrific accident.

About 250 people, including dozens of teenagers, packed into Third Avenue United Church to remember the Grade Eleven student.

Wensley and James (J.P.) Haughey, also 17, died on May 5 when their car was broadsided by a truck that police say was stolen.

A cluster of pink and purple Gerbera daisies and roses sat on top of the teen's casket at the front of the church.

Those who knew Wensley, a student at Bethlehem Catholic High School, described her as an athletic, positive person with an active social life.

Sarah's father Dave Wensley and her older brother Brennan Rowland delivered her eulogy.

The elder Wensley described his daughter as a good friend who gave him many precious memories.

"Having Sarah was like watching a beautiful flower bloom over the years," he told the mourners.

"She just seemed to get more beautiful every year."

During the funeral, Wensley's father said his thoughts and prayers were with the families of the other teens involved.

A 16-year-old girl who was in the car with Haughey and Wensley was badly injured in the crash.

Rowland fought through tears as he shared stories of their time together as children, remembering his constant role as her protector. 

He drew laughter from the crowd as he recalled forgetting his younger sister on the bus as a child, and running after it and stepping in front of the vehicle to get her back

"I am the bush and she was the bird," Rowland said. "The bird, with all of its problems, can always find solace and solutions in the bush. Now she is our bush," Rowland said as he ended the eulogy.
