Delete User from Table AspNetUsers MVC5

As I can delete users that I created in the AspNetUsers table, I work under MVC5.

My code is as follows,

AccountController.cs:

 //INDEX LIST USERS ADM
        public ActionResult Index()
        {
            userContext = new ApplicationDbContext();
            List<AspNetUserstb> users = (from o in userContext.Users
                                         join p in userContext.Roles on o.Roles.Select(t => t.RoleId).FirstOrDefault() equals p.Id
                                         select new AspNetUserstb
                                         {
                                             Id = o.Id,
                                             Email = o.Email,
                                             Rol = p.Name
                                         }).ToList();

            return View(users);
        }

My sight.

Index.cshtml:

<h2>Usuarios SI</h2>

<p>
    <button onclick="location.href='@Url.Action("Register")'" type="button" class="btn btn-success">Nuevo Usuario</button>
</p>
<div class="stylepagination">
    <table id="usersadm" class="table nowrap table-bordered table-hover display">
        <thead>
            <tr>
                <th>
                    @Html.DisplayNameFor(model => model.Email)
                </th>
                <th>
                    @Html.DisplayNameFor(model => model.Rol)
                </th>
                <th><span class="glyphicon glyphicon-cog"></span> Administrar</th>
            </tr>
        </thead>
        <tbody>
            @foreach (var item in Model)
            {
                <tr>
                    <td>
                        @Html.DisplayFor(modelItem => item.Email)
                    </td>
                    <td>
                        @Html.DisplayFor(modelItem => item.Rol)
                    </td>
                    <td style="text-align: center;">
                        <div class="btn-group btn-group-sm">
                            <button onclick="location.href='@Url.Action("Resetpw", "Account", new { id = item.Id })'" type="button" class="btn btn-default">Reset Password</button>
                            <button onclick="location.href='@Url.Action("Deluser", "Account", new { id = item.Id })'" type="button" class="btn btn-default">Eliminar</button>
                        </div>
                    </td>
                </tr>
            }
        </tbody>
    </table>
</div>

and finally my model.

    }

        public string Password { get; set; }

        [DataType(DataType.Password)]

        public string ConfirmPassword { get; set; }

        public string Code { get; set; }
    }

    public class ForgotPasswordViewModel
    {
        [Required]
        [EmailAddress]
        [Display(Name = "Correo electrónico")]
        public string Email { get; set; }
    }

    public class AspNetUserstb
    {
        [Display(Name = "Id")]
        public virtual string Id { get; set; }

        [Display(Name = "Correo electrónico")]
        public virtual string Email { get; set; }

        [Display(Name = "Rol")]
        public virtual string Rol { get; set; }
    }
}

The only thing I need is to delete the user that I select in the table that I currently have, that table has the delete button and that button has the id of the user that I want to remove from the AspNetUsers table.
