Vicksburg Police Chief Tommy Moffett says this week's arrest of four brothers for murder shows
Mississippi needs stricter penalties for violent crimes.
Two of the brothers, Anthony Lydell Trevillion and Armond Henry Trevillion, have already served prison time for other slayings.
They along with their other two brothers -- Alonzo Leemont Trevillion and Matthew Ladale Nash -- are charged in Sunday's shooting death of Justin Maurice Harris.
Vicksburg police said Harris' killing followed an argument over a woman that began outside the New Orleans Cafe in Vicksburg.
Armond and Anthony had served prison time on aggravated assault charges, even though they had been indicted on two counts of murder involving 1996 shooting deaths.
Both were sentenced to prison - Armond to serve 10 years and Anthony to 15.
Armond was freed in September 2003 on earned release and Anthony was freed in March 2006 on earned release, according to prison records.
