Delete Multiple Records from Multiple Tables

What is the simplist/correct way to delete multiple records from multiple tables. Any help appreciated. Thanks! (Yes, I'm totally new to this.)

delete dbo.tblcase

where dbo.tblcase.case_id in ('299760', '299757', '299739', '299732', '299902',
'299901', '299897', '299894', '299873', '299872', '299870', '299865', '299860',
'299858', '299854', '299846', '299838', '299834', '299821', '299813', '299803')

delete dbo.tblcaseclient

where dbo.tblcaseclient.case_id in ('299760', '299757', '299739', '299732', '299902',
'299901', '299897', '299894', '299873', '299872', '299870', '299865', '299860',
'299858', '299854', '299846', '299838', '299834', '299821', '299813', '299803')

delete dbo.tblcaseinformation

where dbo.tblcaseinformation.case_id in ('299760', '299757', '299739', '299732', '299902',
'299901', '299897', '299894', '299873', '299872', '299870', '299865', '299860',
'299858', '299854', '299846', '299838', '299834', '299821', '299813', '299803')

delete dbo.tblcaselawyer

where dbo.tblcaselawyer.case_id in ('299760', '299757', '299739', '299732', '299902',
'299901', '299897', '299894', '299873', '299872', '299870', '299865', '299860',
'299858', '299854', '299846', '299838', '299834', '299821', '299813', '299803')

delete dbo.tblcaseprosecutor

where dbo.tblcaseprosecutor.case_id in ('299760', '299757', '299739', '299732', '299902',
'299901', '299897', '299894', '299873', '299872', '299870', '299865', '299860',
'299858', '299854', '299846', '299838', '299834', '299821', '299813', '299803')The simplest method is to establish relationships between your case table and the child tables, and define those relationships to have cascading deletes.
Then just delete from your case table and let SQL Server handle the rest.
