No security cameras took his picture. Frightened tellers facing his gun and knife had no silent alarms to press.

In a matter of minutes Friday afternoon, a robber entered a trailer-house bank here, brutally killed three bank employes and a young farmer, seriously injured the manager of the next-door cafe and shot a man and wife before his gun failed to fire on their 1-year-old daughter.

Fleeing through the cold mist in a blue sedan, the robber, described by the survivors as a frenzied, shaggy-haired man wearing wire-frame glasses, has eluded an elaborate federal and state manhunt extending south to Texas across the rutted roads and muddied green wheat fields that surround this shocked hamlet 100 miles southwest of Oklahoma City.

Now, Geronimo's 800 residents, a mix of farmers, Indians and blue-collar workers, are living with suspicion and distrust. Citizens troubled days ago only by salt in well water and stray dogs now say they sleep with shotguns.

"We don't want to stay here, but we have to," said Billie Coast, wife of the town's Baptist minister.

"I have a bad habit of leaving my key in the door," said Donna Lawler, who lives with her husband and 2-year-old son in an Apache Indian subsidized house. "I decided not to do that anymore."

While sheriff's deputies armed with high-powered rifles patroled the dozen paved roads that traverse Geronimo, citizens gathered at the town hall across from the closed First Bank of Chattanooga and volunteered to join the search.

"I don't want to find that man," growled Travis Kinder, a farmer who offered deputies advice. "He would do better with the police."

The minister, Eddie Coast, will lead funeral services in the high school gym Monday and Tuesday for three of the victims, bank tellers Jeri Bowles, Joyce Mullenix, who was six months pregnant, and farmer Ralph E. (Eddie) Zeller, who had stopped by the bank to deposit a government check. Services for bank manager Kay Bruno will be in nearby Lawton, where she lived.

Reuben Robles, 20, and his wife, Bellen, 15, were in a Lawton hospital with superficial wounds, a spokesman said, while cafe manager Marilyn Roach, 24, was listed in serious condition in an Oklahoma City hospital after surgeons removed two bullet fragments from her brain Friday night.

"His pickup was still running outside the bank ," Zeller's mother, Mary Jean, recalled as she sat among grieving family and friends in the Zellers' clapboard farmhouse a dozen miles west of here.

"There ought to have been a camera in there," said Fred Wyatt, Zeller's first cousin. "At least then we'd have a picture of him the robber ."

Just before 1:30 p.m. Friday, one of Roach's fellow employes at the Blue Jay Drive-In discovered the bodies and the Robleses' crying baby in the back room of the bank, where their assailant had lined them up and shot each in the head and stabbed some in the neck.

"My son told me he also pulled the trigger on the baby, but the gun was out of bullets," Jose Robles, Reuben's father, told reporters. "About four or five times he pulled the trigger."

Based primarily on interviews with the Robleses, who with Zeller apparently interrupted the robbery, investigators made a composite drawing and a psychological profile.

According to the profile, the robber, 19 or 20 years old, could be a loner and high school dropout with a history of sporadic employment in manual labor and of drug and alcohol abuse. He likely stayed up all night before the robbery.

According to the profile, he can exhibit unpredictable behavior. He may always act against smaller and weaker persons and be prone to carry a knife or gun to impress associates who are usually younger than he, and he sometimes threatens them. If he has a girlfriend, she is younger. The week before the robbery, he would have been totally disorganized, exhibiting little or no personal hygiene.

He took more than $3,000, investigators said.

"Obviously, it would have helped considerably to have a photograph," said Anthony Daniels, the FBI special agent supervising the hunt. "An alarm system would have increased the response time on the robbery."

"We had the security we were required to have," said Bill Crawford, chairman of the bank's board, who noted that the bank had an alarm to disrupt after-hours robberies.

"There's no amount of security measures that can stop somebody like that," said Bob Empie, Oklahoma's banking commissioner. "You're dealing with a very, very vicious person who has no regard whatsoever for laws or security measures."

The bank, which opened last February, operated under a new state law allowing branch banking that stipulates no security requirements, only that the branch be within 25 miles of its main bank and be in an "unbanked" town, Empie said.

In a double-wide trailer home, it sits on Main Street across from a store and town hall and next to the Blue Jay Drive-In Roach managed.

"They're little old hazard traps," said Kenneth Alexander, a banker for 32 years and president of Security National Bank in Lawton. "I and others predicted this sort of thing when these branches came in."

Geronimo's citizens will be asked whether they want the bank to reopen, Crawford said. "We'll just talk to town leaders," he said. "I'm sure there's one or two around."

"I just can't make myself walk in there and be vulnerable," said Don Duggins, a Geronimo school administrator who said he had taught Zeller and Roach. "When you walk in there, you won't help but think, 'Lord, the same thing could happen to me.' "
