A local Minneapolis man allegedly used a sword to murder his mother and nephew on Monday, Abby Simons reported.
A criminal complaint filed Wednesday stated that Ishmael Roberts, 22, calmly walked into his mother's home in north Minneapolis and killed his mother, Beatrice Wilson, 57, and nephew, Peter, 14, with a samurai sword, Simons wrote.
Police say that the injuries on the two victims indicate that they put up a fight.
"They had multiple lacerations, and the lacerations they had were indicative of a struggle and a vicious fight," said Minneapolis Police Capt. Amelia Huffman.
Police are hinting at mental illness as a possible cause for the tragedy.
