This Amendment No. 8 to Schedule 13D (this "Amendment") is being filed
by Cadell S. Liedtke (the "Reporting Person") to reflect a change in the
beneficial ownership of the Reporting Person of the Common Stock, $0.10 par
value (the "Common Stock"), of Costilla Energy, Inc. (the "Company") from such
beneficial ownership reflected in the Schedule 13D filed by the Reporting
Person on October 18, 1996, as amended by Amendment No. 1 to Schedule 13D filed
by the Reporting Person on November 15, 1996, by Amendment No. 2 to Schedule
13D ("Amendment No. 2") filed by the Reporting Person on November 3, 1998, by
Amendment No. 3 to Schedule 13D filed by the Reporting Person on January 8,
1999, by Amendment No. 4 to Schedule 13D filed by the Reporting Person on May
19, 1999, by Amendment No. 5 to Schedule 13D filed by the Reporting Person on
June 10, 1999, by Amendment No. 6 to Schedule 13D filed by the Reporting Person
on July 29, 1999 and by Amendment No. 7 to Schedule 13D filed by the Reporting
Person on August 19, 1999 (collectively, the "Original 13D").
The changes in the percentage of beneficial ownership reported herein
are the result of shares beneficially owned by the Reporting Person which have
been involuntarily sold pursuant to financing arrangements since Amendment No.
7 (see Item 5 hereof).
Only those items of Schedule 13D, or portions thereof, being amended
are included in this Amendment. Except as expressly amended and modified by
this Amendment, the Original 13D remains unchanged and in full force and
effect.
ITEM 5. INTEREST IN SECURITIES OF ISSUER
(a) As of August 31, 1999, the Reporting Person beneficially owned
828,460 shares of Common Stock constituting 5.9% of the total issued and
outstanding shares of Common Stock (14,101,580 shares).
(b) The Reporting Person has the sole power to vote or to direct the
vote and the sole power to dispose or direct the disposition of all of the
shares of Common Stock attributed to the Reporting Person in paragraph (a) of
this Item 5, except for 60,000 shares held by the Liedtke Foundation (as
hereinafter defined). The Reporting Person is a director of the Liedtke
Foundation and shares voting and dispositive power over the shares of Common
Stock owned by the Liedtke Foundation with the other directors of the Liedtke
Foundation.
(c) The Reporting Person financed certain purchases of shares of

Command Account Margin Agreement (the "Account Agreement"). The Marion and
Cadell S. Liedtke Family Charitable Foundation (the "Liedtke Foundation"),
through which the Reporting Person beneficially owns shares, has also entered
into an Account Agreement with Prudential. The form of Account Agreement
entered into between Prudential and the Reporting Person and the Liedtke
Foundation is substantially similar in all material respects (other than the
name of the accountholder, the date of execution, and other details), and a
copy of the form of the Account Agreement was attached as an exhibit to
Amendment No. 2 and is incorporated herein by reference for a description of
the terms of the financing arrangements pursuant to which the Reporting Person
has borrowed funds for the purchases of Common Stock. To further secure

Prudential whereby the Reporting Person has pledged certain of the shares of
Common Stock owned by the Reporting Person. A copy of the form of Pledge
Agreement was attached as an exhibit to Amendment No. 2 and is incorporated

Common Stock by the Reporting Person, which include the right to sell shares
under certain circumstances.
