(AP) — Police say an Omaha man stabbed his on-again, off-again girlfriend more than 45 times before he tried to leave the state.

A Douglas County judge ruled Wednesday that there’s enough evidence to try 32-year-old Robert W. Grant on a charge of first-degree murder.

Grant is accused of killing 43-year-old Trudy McKee in September. The woman’s teenage daughter found her body in their apartment. A murder weapon has not been found.

Omaha police arrested Grant later in the day after he boarded a Chicago-bound bus. Omaha police detective Thomas Queen testified that blood found on Grant’s shoes tested positive for McKee’s DNA.

A message left for Grant’s attorney was not immediately returned.
