An argument at a north side gas station early this morning left one man in critical condition with multiple stab wounds, News Radio 1200 WOAI reports.
The argument began as the pair were gassing up at the Shell station at Loop 410 and Vance Jackson about 1AM.
One of the men pulled a knife and stabbed the other multiple times, police said.
The victim stumbled into the station where the night manager called 9-1-1.
The assailant sped away in his car and remains at large.
