The body of a man identified as Thomas Schäfer, the finance minister of the German state of Hesse, was found on a high-speed train line in the town of Hochheim between Frankfurt and Mainz, police confirmed Saturday.

The presence of a body on the tracks was first reported by witnesses to paramedics, who were unable to initially identify the remains due to the extent of the injuries.

Investigators said an investigation on the scene confirmed the identity of the man as Schäfer and that the death was likely a suicide. Police did not immediately release further details of the case.

The politician apparently left a note before taking his own life, German daily Frankfurter Allgemeine Zeitung reported, citing sources close to the investigation. The note, according to the report, referenced Schäfer's reasons for his apparent suicide.

According to media in the state of Hesse, the 54-year-old regularly appeared in public in recent days, for example, to inform the public about financial assistance during the coronavirus crisis.

Schäfer had "considerable worries" over COVID-19

Schäfer was a member of Chancellor Angela Merkel's center-right Christian Democrats (CDU). He had been active in Hessian state politics for more than two decades and was finance minister for almost 10 years.

Germany's financial capital, Frankfurt, lies in Hesse and is the state's biggest city.

Schäfer had been widely expected to succeed state premier, Volker Bouffier, if he decided not to stand for re-election in 2023.

In a statement, Bouffier said that the state's leadership has received the news with "sadness and disbelief."

Bouffier also said that Schäfer had been living under considerable worry and stress because of the current COVID-19 pandemic.

"His main concern was whether he could manage to fulfill the huge expectations of the population, especially in terms of financial aid," Bouffier said on Sunday. "He clearly couldn't see any way out. He was desperate, and so he left us. That has shocked us, has shocked me."

"Our sincere condolences go to his closest relatives," he added.

Outgoing CDU chief Annegret Kramp-Karrenbauer said Schäfer's sudden death "shocked me, shocked all of us" in the party. "It has hit us and left us sad and stunned," she wrote on Twitter.

One of the candidates to succeed Kramp-Karrenbauer as leader of the party, Friedrich Merz, and possible successor to Merkel as chancellor wrote on Twitter about his shock at the death.

"News about the sudden death of Thomas Schäfer has deeply shaken me," Merz wrote on Twitter. "As a person and politician he was one of our best – this is a difficult loss. We will mourn him with his wife and children."

Lawmakers from other parties also paid tribute to Schäfer.

Left party member of the Bundestag Fabio De Masi wrote on Twitter "We often no longer recognize politicians as people or the burdens they carry away from politics."

Green politician Kordula Schulz-Asch wrote "I am stunned by the death of Thomas Schäfer. My deepest condolences and thoughts to his family at this time."

Schäfer leaves behind a wife and two children.
