Adelaide Crows coach Phil Walsh was found dead at his home and his son is the prime suspect.

The Adelaide Football Club mourns today as its newest coach was found with multiple stab wounds early Friday morning. His 26-year-old son has been charged with the murder.

According to the police, the son arrived home at 2 am local time and around this time an argument ensued. South Australian Police Superintendent Des Bray told BBC that someone from the household called emergency services for help.

“There’s been an argument, I can’t tell you anything about the argument…but as a result of that both Mr Walsh and his wife received a wound and the wound ultimately caused Mr Walsh’s death,” the police said. Superintendent Bray also confirmed that a knife was found at the scene.

Paramedics arrived in time to find Walsh fighting for his life, but he later died at the scene, notes ABC News. His wife, who also received lesser injuries, was taken to a nearby hospital.

Reports say the son, who The Australian identified as Cy, fled the murder scene but police were able to find him. He has been detained for psychiatric assessment.

“We can’t speak to the son at this stage and obviously [the] wife is receiving treatment so as the investigation unfolds, I’m sure we’ll find out exactly what happened,” Superintendent Bray explained, notes ABC.

The Adelaide Crows as well as the entire Australian Football League was shocked by the news. The Crows released a statement earlier, saying they will be having a media conference this afternoon.

“The Adelaide Football club is devastated at the sudden passing of senior coach Phil Walsh in the early hours of this morning…We ask if you could please respect the privacy of his family, as well as our players, coaches and staff, at this extremely difficult time.”

The Crows vs Geelong match is scheduled for Sunday, however, it may be unlikely that the match will continue.
