(06-17) 19:07 PDT TURLOCK (STANISLAUS COUNTY) -- The town of Turlock and much of the rest of the nation was shocked when a 27-year-old man beat and stomped his 2-year-old son to death on a rural road. But what was nearly as stunning for many people was that none of the motorists and their passengers who stopped and saw the attack tried to tackle the man.
Police officers and psychologists familiar with violent emergencies, however, said they weren't surprised at all.
A volunteer firefighter and at least five others saw Sergio Casian Aguiar assaulting his son Saturday night on the road west of Turlock (Stanislaus County), but it wasn't until a police officer arrived in a helicopter that the attack finally ended. Aguiar refused to halt the attack and raised his middle finger at the officer, who shot him to death, authorities said.
Bystanders are justifiably scared and confused in such situations, the experts said Wednesday, and they lack the experience needed to respond with force. They can also be mesmerized by shock.
John Conaty, a veteran homicide detective and former patrol officer in Pittsburg, said that in interviews of witnesses to violence, "the common thing you hear is, 'I was frozen in fear. I just couldn't take action.' "
Conaty questioned whether the witnesses had even been capable of stopping Aguiar. "If they were physically able, you have to take a look at whether they were psychologically prepared to intervene," he said.
"I would not condemn these people," said John Darley, a professor of psychology and public affairs at Princeton University who has studied how bystanders react in emergency situations. "Ordinary people aren't going to tackle a psychotic.
"What we have here," Darley said, "is a group of family and friends who are not pre-organized to deal with this stuff. They don't know who should do what. ... If you had five volunteer firefighters pull up, you would expect them to have planned responses and a division of labor. But that's not what we had here."
Darley said he was also not surprised that people who weren't at the scene of the killing believe they would have been heroic Good Samaritans.
"It's an aspiration," he said. "They hope they would have done differently."
First on the scene
One of the witnesses, Deborah McKain of nearby Crows Landing, said she was the first to pull up to the beating scene
with her boyfriend, a volunteer fire chief who is 52, as well as her 20-year-old son, her son's wife and
her son's male friend. They called 911 at 10:13 p.m., police said.
Over the next seven minutes, McKain said, Aguiar kicked his son at least 100 times as he calmly stated that he needed to "get the demons out" of the boy.
"It was like I was on some type of drug or something," McKain recalled Tuesday. "I couldn't believe what was going on. It was like a dream."
She said her boyfriend, Dan Robinson,
forcefully argued with Aguiar in an effort to get him to stop, but that he would not. At one point, another woman, 23-year-old Lisa Mota, pulled up in her car, but stayed inside.
"We were looking for rocks or boards on the ground, just to knock him out, get him under control. But we couldn't find anything," McKain said. "We didn't know if he had a knife or any kind of weapon on him."
McKain said she wondered whether Aguiar was on hallucinogenic drugs and whether fighting with him might lead him to hurt several of the witnesses.
She also said it appeared the child was "gone."
People who are second-guessing her and her family can "never know until they're in that situation," McKain said. "We would have loved to knock his head off, too, but we had nothing to knock it off with."
Deputy Royjindar Singh, a spokesman for the Stanislaus County Sheriff's Department, acknowledged there was some "Monday morning quarterbacking" taking place, but said his agency had no problem with the actions of the witnesses.
'Everybody acts differently'
"Your headlights are shining on a person taking the life out of an infant, and not just shaking and slapping but punching and kicking," Singh said. "Everybody reacts differently."
Sheriff's investigators are still trying to determine why Aguiar, a grocery store worker who recently split up from his schoolteacher wife, killed his son so savagely. The boy's name still has not been released.
Investigators have learned that Aguiar left his home near downtown Turlock before the beating, but they don't know why he drove about 10 miles into an area of cornfields and dairy ranches, Singh said. He said investigators had found no evidence of drug use at Aguiar's house or in his pickup, though results of toxicology tests have not yet come back.
Aguiar's wife, who was in Southern California at the time of the slaying, and others have told investigators that Aguiar "wasn't acting differently than how he normally acts," Singh said. Aguiar's family members, who live in Mexico, were traveling to Stanislaus County to talk to deputies, Singh said.
"As of right now," Singh said, "nobody's saying he was having problems at all. It's baffling.
It sounds like there was nothing anyone could have done." (WTF!!!?)
