KEARNEY, Neb. (AP) — The 58-year-old Nebraska man charged with killing his former divorce lawyer and his ex-wife earlier this month had numerous guns and ammunition stockpiled.

Authorities searched Michael Petersen’s property near Glenvil after the Nov. 13 shootings.

Authorities 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.

Petersen has been charged with two counts of first-degree murder. Prosecutors say he used a rifle to shoot Nancy Petersen outside her home in Buffalo County and then drove to Grand Island and killed 52-year-old lawyer Todd Elsbernd.

Elsbernd represented Michael Petersen in his 2005 divorce.

Petersen’s preliminary hearings are scheduled for Jan. 21.
