A University City man who was stabbed to death with scissors on Monday was allegedly attacked by his same roommate in another assault case from 2018, the prosecutor said on July 10. Brandon Ganskow, 34, pleaded not guilty July 10 to the murder of Kevin Crosthwaite, 56, who was killed in the house in the 5300 block of Bothe Avenue in University City. Ganskow and his mother both lived with Crosthwaite and she attended his arraignment before San Diego Superior Court Judge Jay Bloom. Ganskow stabbed Crosthwaite “a number of times” in the neck with scissors, said Deputy District Attorney Matthew Greco, who added that Crosthwaite died of cardiac arrest and loss of blood. The prosecutor told Bloom Crosthwaite was stabbed with a knife in 2018 by Ganskow who was sentenced to jail and released on terms of probation. Ganskow was able to return to the same residence with the victim’s consent in 2019, said Greco. “He was a victim who had a big heart,” said Greco afterwards to reporters. “Unfortunately, on July 8, history repeated itself in a very sad way.” San Diego Police reported getting a call at 6:13 a.m. on July 8 for a person who was not breathing. Crosthwaite could not be revived and officers interviewed Ganskow and his mother before Ganskow was later arrested. Bloom set bail at $3 million on the murder case, but revoked bail on the probation case because he had violated terms of his probation by being arrested again. Ganskow remains in jail. A preliminary hearing was set for Sept. 26.
