CHEYENNE, Wyo. (AP) — A lawyer representing a man accused of killing two people and wounding a third in a shooting rampage at his house last summer wants to seal the court records.

Nathaniel Castellanos' (CAS-tee-yah-nohs-ehs) attorney has asked a judge to seal the prosecution's notice that it intends to seek the death penalty and other records in the case. The judge hasn't yet decided whether to hold a hearing on the request.

Prosecutor Mike Blonigen said Tuesday that the request "doesn't really cite any real authority" for asking to seal the records.

Castellanos pleaded not guilty in October to two counts of first-degree murder and one count of attempted first-degree murder.

Castellanos is accused of fatally shooting 21-year-old Corey A. Walker and 25-year-old Megan L. McIntosh, both of Cheyenne, on Aug. 23 in Castellanos' home on Cheyenne's northeast side. Another woman, 23-year-old Amber J. McGuire, was wounded.
