A Sikh congregation in central California is reeling after a 64-year-old member was stabbed to death while out walking this week.

Parmjit Singh was reportedly taking a routine Sunday night walk near Tracy’s Gretchen Talley Park when he was attacked. He was left bleeding on the street and was pronounced dead at the scene, local police confirmed.

Tracy police say there’s no evidence that the homicide was motivated by race or religion.

“Any such inference is completely inappropriate at this point,” said Tracy’s interim police chief, Alex Neicu. “Of course, like any other thorough investigation, we consider all possibilities and motives, but we follow where the evidence leads us.”

Singh immigrated to the U.S. from India in 2016, CBS Sacramento reports. He lived with his daughter and son-in-law in Tracy and had three grandchildren.

The crime has deeply shocked members of Tracy’s Sikh community, according to Deep Singh, secretary of the Sikh gurdwara, or house of worship, that Parmjit Singh attended. He said relations between the city’s various religious communities are generally very strong.

“This was never expected in Tracy, because it doesn’t matter which religion, which race anybody belongs to, they go along together very easily,” Deep Singh said.
