NORFOLK, Va. (CBS News) — Four service members of the United States Navy have died by suicide between July and September of this year, officials have confirmed. The suicides involved four sailors assigned to the USS George H.W. Bush aircraft carrier. Although two of the sailors killed themselves on the same day, the suicides did not occur on board the ship and authorities have said there is nothing to indicate the deaths are linked.

In a Facebook post, Captain Sean Bailey, Commanding Officer of USS George H.W. Bush, confirmed that a number of suicides have taken place by crew members in the last two years.

“It is with a heavy heart that I can confirm the loss of three Sailors last week in separate, unrelated incidents from apparent suicide. My heart is broken,” Bailey wrote. “These deaths mark the third, fourth, and fifth crew member suicides in the last two years. Now is the time to come together as a crew and as a family to grieve, to support each other, and to care for those in need.”
