A 45 year old south side man is in very critical condition after police say he was repeatedly stabbed--by his 27 year old son.
It happened at the man's home in the 1200 block of Division.
Detectives say the two men were arguing when the son pulled a knife and stabbed his father multiple times...the bolted and ran away.
The victim was rushed to the hospital with multiple stab wounds.
The suspect is on the loose but police know who he is and an arrest is expected soon.
