Did i use GetPlayerFromCharacter() correctly?

Script inside workspace:

local humanoid = game.Workspace.Speler.Humanoid
game.Players.PlayerAdded:connect(function(player)
    player = player
end)
humanoid.MaxHealth = 0
humanoid.Health = 0
humanoid.HealthChanged:connect(function(health)

    local players = game:GetService("Players")
humanoid.Parent.Head.Touched:connect(function(otherpart)
if otherpart.Name == "Handle" then
    local character = otherpart.Parent.Parent
    local player = character:GetPlayerFromCharacter()

    local replicatedstorage = game:GetService("ReplicatedStorage")
    local remote = Instance.new("RemoteEvent", replicatedstorage)
    remote:FireClient(player)

end
end)

end)

The error Roblox from Roblox Studio: GetPlayerFromCharacter is not a valid member of Model

I think i used GetPlayerFromCharacter() incorrectly(line 13).
