DOWAGIAC, Mich.-- Custodian Jennifer Grindstaff says she did what anyone else would have done: followed her gut instinct when she spotted a boy hiding across from Dowagiac Middle School parking lot in the woods.

"I just kept watching him and as I started walking towards the building I saw him run towards the South Side of the building," said Grindstaff, substitute custodian.

Once inside, Grindstaff quickly found the principal who then watched surveillance video. She says the video showed the boy near the dumpsters with a hand gun. After alerting police, the principal placed the district's schools on lock-down and halted the buses from arriving.

"They ran towards us and yelled shots fired shots fired and then we went to a room in the office," said Grindstaff.

Thirteen-year-old Darren Price shot himself in the woods and later died at the hospital.

"I'm glad nobody else got hurt, but I'm sad that he had to take his own life," said Grindstaff.

Stuffed animals and a cross now sits at the opening in the woods where the custodian first spotted Price. Former classmate Breanna Bannow and friends left them in remembrance of him because he struggled with constant bullying.

"But he handled it pretty well but then he started getting into a lot of trouble because he started getting fed up with the kids picking on him so much," said Bannow.

She wants others to remember that her classmate tried his best to cope with the bullying.

"No matter how much he got picked on--he was always fun to be around," said Bannow.

Extra police officers and counselors were on hand at the school Tuesday. Few details are known about Price's motives, his family or school life. Police say Price got the gun from his Dowagiac home. The weapon had three rounds, including the bullet that took his life.
