According to the report, it ultimately took three tranquilizer darts and eight rounds to put down the lion, named Matthai.

The report details the timeline of events as follows:

• Deputies arrived at the scene after receiving a call about an animal attack
• They made contact with the CEO of the center, Douglas Evans
• He said that a tranquilizer gun was on the way to put the lion down
• The fire department said they had hoses set up to spray the lion if he got too close to the victim, whose body had not been retrieved
• The tranquilizer gun arrived, however, while Evans was preparing the dart with medication, the dart broke and they couldn't get the broken part back out of the gun
• Evans then left to get another gun
• Evans came back, this time with a blow dart. He told deputies that he retrieved it from his home, where he keeps the darts and medication
• Evans blew two darts, which hit the lion but appeared to have no effect
• While he was preparing a third dart, the lion jumped from one platform, down to the ground and then to the top of another structure
• Evans hit the lion with a third dart. The lion jumped off the structure and then went inside the structure and laid down. After a few minutes, the lion still showed no signs of sleepiness
• A firefighter then tried to use a hose to get the lion out of the structure and into the safety enclosure but the attempt failed and the lion started moving toward the victim once again
• The lion passed by a sergeant at the scene and the sergeant shot the lion, using a 12 gauge shotgun, near the front right shoulder
• The lion did not go down but instead ran back into the wooden structure
• The sergeant fired a second time, hitting the lion in the same area. The lion did not go down. Another lieutenant put a third shot in the same area. After a few minutes, the lion still would not go down
• The sergeant fired a fourth shot into the lion's right side. The lion moved inside the structure but still did not go down
• The lion then came outside the structure and ran toward the fence where the deputies were standing. The sergeant put a fifth and sixth bullet into the lion but the lion continued to run.
• One of the deputies then shot the lion in the base of the neck, and he finally went down. A few minutes later, the lion stopped breathing.
• Evans told the sergeant that he would need to shoot the lion in the heart to make sure he was dead
• The sergeant then shot the lion in the heart.
• Evans went into the enclosure and confirmed that the lion was dead
• EMS went into the enclosure and confirmed that 22-year-old Alexandra Black had died from her injuries.
