A software engineer who works for Google is facing a murder charge after he allegedly beat his wife to death with his bare hands.

Officers in Santa Clara, California, responded to a home around 11 a.m. Tuesday for a well-being check. When officers arrived they met with an acquaintance of 27-year-old Liren Chen and his wife who was concerned for their safety. Chen wasn’t answering his phone or the door. The acquaintance told officers he saw Chen inside the home, “motionless on his knees, had his hands in the air and was staring blankly,” a press release said.

Cops entered the home and took Chen, who was splattered in blood, into custody. They found Chen’s wife directly behind where he was standing in a bedroom. She was suffering from severe blunt force trauma to her head and paramedics pronounced her dead on scene. Chen’s right hand was extremely swollen and purple and he had blood on his clothing, legs, arms, and hands. He also had scratches on his arm, authorities said.
