New developments have been uncovered in the case against Michael Petersen.
Numerous guns and a stockpile of ammunition were found in the 58-year-old Nebraska man's home. Petersen was charged with killing his former divorce lawyer and his ex-wife earlier this month.
Authorities searched Petersen's property near Glenvil after the Nov. 13 shootings and found at least a dozen guns, 13 boxes of rifle bullets and more than 100 other bullets and shells. The vehicles authorities believe were used in the shootings were also found in the search.
Petersen has been charged with two counts of first-degree murder, one in Buffalo Co. for the alleged murder of his ex-wife Nancy Petersen and the other in Hall Co. for the alleged murder of attorney Todd Elsbernd.
Prosecutors said he used a rifle to shoot Nancy outside her home in Kearney and then drove to Grand Island and where he killed Todd Elsbernd.
Elsbernd represented Michael Petersen in his 2005 divorce to Nancy.
Petersen's preliminary hearings are scheduled for Jan. 21.
