How to work with deleted records?

Example: I created business process where start signal is "delete record". After this signal I need to delete data from other object, that contains parameters contact and account from deleted record.

But as far as I can see, parameters form deleted record cannot be used as they are not existing or something like that:

    "Параметри процесу": [
        {
            "Параметр": "контраг",
            "Значення": {
                "Перед виконанням": "00000000-0000-0000-0000-000000000000",
                "Після виконання": "00000000-0000-0000-0000-000000000000"
            }
        },
        {
            "Параметр": "ртп зч",
            "Значення": {
                "Перед виконанням": "00000000-0000-0000-0000-000000000000",
                "Після виконання": "00000000-0000-0000-0000-000000000000"

Is it possible to work with parameters form deleted record via business process or it is possible only using coding?
