Argonia ? An impromptu memorial for a teenager hit and killed by a train earlier this month under suspicious circumstances is continuing to grow along the section of railroad tracks where he died.

Meanwhile, authorities investigating the death of Jacob “Jake” Allen, 19, of Argonia, continue to refuse to provide details about his death, or say whether they consider it a homicide.

“Right now, we’re not ruling out anything,” Sumner County Sheriff Gerald Gilkey said Tuesday.

Allen’s nude body was found early on July 5 along the Burlington Northern Santa Fe Corp. tracks a few miles east of Argonia. His black sweatshirt and red sweatpants were farther down the line.

Various law enforcement and railroad sources connected with the investigation have said Allen, who graduated as Argonia High School’s valedictorian in May, apparently had been tied with baling wire to the tracks.

At the memorial along the tracks, there are pictures, more than 20 floral bouquets, wreaths, angel figurines, a wooden cross, a basketball bearing the names of Allen’s teammates and a sealed envelope with “My Jake” written on it.

On the cross are the words “God, we hurt.”

Rebecca Salsbery, who lives near the crossing where the body was found, said many people drove to the site, walking along the tracks, looking dazed and consoling one another.

“You would think it would slow down, but it hasn’t,” she said.

Allen, who graduated in May at the head of his 14-member class, was a National Honor Society member and competed in football, basketball and track. He planned to attend Northeastern Oklahoma University.

“He’s very responsible, and he wouldn’t leave his house in the middle of the night,” said Carissa Stansbury, a classmate and friend. “No one hated him at all. … He had his whole life planned out.”

Stansbury said she talked with Allen about 7:40 p.m. on July 4, urging him to join her and others at Anthony Lake. She said Allen declined, saying he was going to stay home and shoot off fireworks with his family.

“I’ll call you first thing tomorrow morning,” she quoted him as saying.

The sheriff, aware of frustration over lack of information about the case, asked for patience.

“Two weeks is not an extraordinary amount of time to be working on a case like this,” he said. “It’s not ‘CSI’ and ‘NYPD Blue.’ It’s not going to happen in an hour.”

Gilkey said his investigators, who are assisted by the Kansas Bureau of Investigation, are taking steps to be thorough and that other agencies “are going over our work so we don’t miss anything.”

“This is an out-of-the-ordinary situation, and we have only one chance to do it right,” he said.
