2 Chronicles 22:9

“he sought Ahaziah, and they caught him (for he was hid in Samaria)--(compare Kg2 9:27-29). The two accounts are easily reconciled. "Ahaziah fled first to the garden house and escaped to Samaria; but was here, where he had hid himself, taken by Jehu's men who pursued him, brought to Jehu, who was still near or in Jezreel, and at his command slain at the hill Gur, beside Ibleam, in his chariot; that is, mortally wounded with an arrow, so that he, again fleeing, expired at Megiddo" [KEIL]. Jehu left the corpse at the disposal of the king of Judah's attendants, who conveyed it to Jerusalem, and out of respect to his grandfather Jehoshaphat's memory, gave him an honorable interment in the tombs…”

“Compare the marginal reference. Ahaziah after remaining a while at Megiddo, removed to Samaria, where his wounds could be better cared for and concealment might be easier; Jehu’s emissaries discovered him there; they took him to Jehu, who happened at the time to be at Megiddo; and then and there Jehu put him to death.

"The current of the story at large is this," says Dr. Lightfoot: "Jehu slayeth Joram in the field of Jezreel, as Ahaziah and Joram were together: Ahaziah seeing this, flies, and gets into Samaria, and hides himself there. Jehu marches to Jezreel, and makes Jezebel dogs' meat. from thence sends to Samaria for the heads of Ahab's children and posterity; which are brought him by night, and shewed to the people in the morning. Then he marches to Samaria, and, by the way, slayeth forty-two of Ahab's kinsmen, and findeth Jehonadab, the father of the Rechabites. Coming into Samaria, he maketh search for Ahaziah. they find…”
