Authorities have released a sketch of a suspect in the shooting death of an Arizona priest in an attack on a Roman Catholic church on Wednesday.
The suspect is said to be a white male aged 40-49.
The description came from a second priest who was injured in the attack.
The Reverend Joseph Terra, 56, is in a critical condition in hospital. He administered Last Rites to Father Kenneth Walker, 28, following the break-in at the church.
A $1,000 (£589) reward has been offered for information leading to an arrest in the incident.
'No ill will'
Police went door to door in the neighbourhood looking for potential witnesses on Friday.
Investigators are unsure if more than one suspect was involved or if robbery was a motive in the attack at Mother of Mercy Mission in Phoenix.
A car belonging to Father Walker was found abandoned several blocks from the church after the crime.
