Brothers, 12 and 14, Killed in Compton : Violence: Gunshots erupt as a car chases their vehicle after a party. Investigators say they have few leads.

Two brothers, ages 12 and 14, who had just left a party late Saturday in Compton, were killed by assault weapon shots fired from a car that was chasing the one they rode in, police said Sunday.

Their elder sister was among three others in the car who saw them die.

The attack evoked memories of the Halloween, 1993, shootings in Pasadena in which three teen-age boys were killed and three others were wounded while walking home from a birthday party.

But Compton Police Sgt. John Garrett said it was too soon--and details of the shooting Saturday night were too sketchy--to draw parallels.

The brothers, 12-year-old Bobby Millan and 14-year-old Mario Millan, along with their sister and two others, had just left a party at 138th Street and Wilmington Avenue when they noticed that their truck was being followed by another vehicle, Garrett said. Police said there were several people inside.

Within a few blocks, Garrett said, gunfire erupted from the other car and continued for some time. Late Sunday, police Sgt. Robert Baker said detectives believe the weapon was an assault rifle.

At Rosecrans Avenue and Wilmington Avenue, about half a dozen blocks away, the others in the truck noticed that the brothers, sitting in the back, had been hit. They pulled over and called police at 11:46 p.m., Garrett said.

At 12:08 a.m., the brothers were pronounced dead at the scene, he said. The three others in the truck were not hurt.

The truck, officers said, had bullet holes in the tailgate and windshield.

Garrett added that detectives had very few leads. The youths in the truck could not describe the other vehicle, nor could they say whether there was more than one gunman.

It also remained unclear late Sunday whether the shootings were gang-related, Garrett said.

In an apparently unrelated attack, also in Compton a few miles away, one man was killed and four others wounded Sunday evening, Baker said.

The men were shooting dice about 6:45 p.m. Sunday outside a house on East San Luis Street, Baker said, when a gunman walked up, opened fire and ran away.
