Young sailor's luck runs out

I saw this story in Today's Tribune about a Sailor who was shot to death while he was at home in Englewood on leave. This young man was a husband and an expecting father whose wife is three months pregnant. I really would like to know what happened here. Who shot him and why? Well it's explained in this article...

Witnesses told investigators that four people followed him out of the house, said police spokeswoman Monique Bond. Minutes later, shots were heard and Franklin was found lying in front of the house, she said.

The shooting may have been motivated by retaliation for some earlier grievance, she said, but police were not releasing information about why the men may have disagreed.

Because his son had been gone for nearly two years, Jesse Franklin Sr. said he doesn't believe anyone could have had a grudge against him. His child wasn't involved in gangs and had pushed himself to get away from bad influences, he said.

Very sad a child will never know his daddy.
