Sure.
Fact 1:
Jesus was dead
Mark 15:42-47
42 It was Preparation Day (that is, the day before the Sabbath). So as evening approached, 43 Joseph of Arimathea, a prominent member of the Council, who was himself waiting for the kingdom of God, went boldly to Pilate and asked for Jesus’ body. 44 Pilate was surprised to hear that he was already dead. Summoning the centurion, he asked him if Jesus had already died. 45 When he learned from the centurion that it was so, he gave the body to Joseph. 46 So Joseph bought some linen cloth, took down the body, wrapped it in the linen, and placed it in a tomb cut out of rock. Then he rolled a stone against the entrance of the tomb. 47 Mary Magdalene and Mary the mother of Joseph saw where he was laid.
A centurion in the Roman army was in command of a century of 80 men (excluding the officers) and senior centurions commanded not only their own centuries but the 5 remaining centuries in a cohort. Centurions often supervised crucifixions and this paticular centurion certainly was no stranger to crucifixions like this one. Now some propose that Jesus may have not really died.
John 19:31-37
31 Now it was the day of Preparation, and the next day was to be a special Sabbath. Because the Jewish leaders did not want the bodies left on the crosses during the Sabbath, they asked Pilate to have the legs broken and the bodies taken down. 32 The soldiers therefore came and broke the legs of the first man who had been crucified with Jesus, and then those of the other. 33 But when they came to Jesus and found that he was already dead, they did not break his legs. 34 Instead, one of the soldiers pierced Jesus’ side with a spear, bringing a sudden flow of blood and water. 35 The man who saw it has given testimony, and his testimony is true. He knows that he tells the truth, and he testifies so that you also may believe. 36 These things happened so that the scripture would be fulfilled: “Not one of his bones will be broken,”[c] 37 and, as another scripture says, “They will look on the one they have pierced.”[d]
The centurion was also a witness to this event. From John’s gospel, it was pretty clear to the soldiers that He was dead and a soldier pierced his side as a routine action to make sure.
