A 16-year-old Palo Alto male died on the train tracks early Tuesday morning, Caltrain spokeswoman Christine Dunn has confirmed.

He was struck by the last southbound train just south of the Charleston Road crossing at about 1 a.m., Dunn said.

The Santa Clara County Coroner's Office has identified him as Cameron Lee of Palo Alto.

School district Superintendent Max McGee confirmed Tuesday morning that the teenager was a student at Gunn High School.

McGee sent an email alerting parents at about 8:30 a.m. Tuesday that "a junior from Gunn High School had just lost their life to suicide."

"We have informed all of our schools and our entire staff will be watching for any signs of students who may need support and care following this tragedy," he wrote. "Our counselors are prepared to work with any student or family at a moment's notice, and we ask that you inform your school's principal or psychologist if you believe any child you know is at risk."

Counseling support from the school district's Project Safety Net partners -- nonprofit Adolescent Counseling Services, grief counseling organization Kara and Stanford University Medical Center's Dr. Shashank Joshi -- will be provided at Gunn today, McGee said. The counseling services will also be provided at the schools of the young man's siblings, McGee said.

Palo Alto High School Principal Kim Diorio also sent a message to parents and students, offering on-campus support and resources. Members of Paly's Crisis Response Team were available to meet with individual or groups of students Tuesday as well as in the coming weeks, she said.

At Paly's PTSA general meeting this Thursday at 8:30 a.m., Diorio, the school climate TOSA (Teacher on Special Assignment) and members of the Crisis Response Team will provide information about suicide and mental illness in adolescents, including risk factors and warning signs of suicide, and will answer attendees' questions.

"Students please know we love you and that we are here for you," Diorio wrote. "This is an important time for everyone in our school community to support and look out for one another. If you are concerned about a friend, please be sure to tell a trusted adult. You matter."

Mayor Nancy Shepherd also issued a joint statement with McGee Tuesday evening.

"Our community is shaken at the sad news about this young man's death. We extend our thoughts and prayers to his friends and family," Shepherd said. "I know that our strength comes from the commitment that we all have to support our youth, and we are deepening our partnerships with schools, parents, students, mental health experts, and others.

"Our work to ensure resources, support, and conversations about mental health remains a constant, and we will continue to work through these difficult times as we draw strength from our collective community spirit."

Shepherd said the city has immediately extended the hours for track guards at crossings along the Caltrain right-of-way from the first train in the morning at approximately 5 a.m. to the last train in the evening at approximately 1:15 a.m. The extended hours will include rail crossings at Churchill Avenue, Charleston Road and East Meadow Drive.

Caltrain launched a "There is help" signage program and website with resources for individuals and those seeking to learn more about mental illness and suicide last month. The website can be found here.

Any person who is feeling depressed, troubled or suicidal can call 1-800-784-2433 to speak with a crisis counselor. People in Santa Clara County can also call 1-855-278-4204.

Correction: The location of the fatality was initially reported incorrectly due to inaccurate information from Caltrain. The location was south of Charleston Road.
