SEATTLE Members of the Assumption St. Bridget School community met at the campus chapel Thursday night to remember Melissa Protz, a 6th and 7th grade biology teacher who died in a boating accident Wednesday night.

Well respected by the staff, well loved by the staff, said Jeff Pozarski, school vice principal. She was a great colleague and she ll be terribly missed.

The crash happened on Lake Washington off Leschi around 10:30 p.m. when a speedboat struck the sailboat that Protz was riding in. She died at the scene.

The driver of the speedboat is behind bars on suspicion of homicide by motorcraft. Police say alcohol may have been a factor in the collision.

At the vigil, students expressed their sadness over losing a very popular teacher.

Because of her,I want to be a doctor, said student Wyatt del Valle, She was really amazing. To see someone go like this isn't fair.

The Coast Guard reminds boaters that alcohol on the water can be even more dangerous than on land.

A lot has to do with the heat and being on the water, the waves. You may not realize how much you drank, said Katelyn Shearer, U.S. Coast Guard.

Other people on the sailboat were also hurt. One remains in the hospital in serious condition.
No one on the speedboat was injured.
