持ち物 ('belongings, possessions') is a noun built from the verb stem 持ち- ('hold, carry') + 物 ('thing') — a clean example of the verb-stem-plus-noun compound. 家出する ('to run away from home, leave home') is itself a noun-as-verb compound: 家 ('home') + 出 (verb stem of 出る 'leave') + する. The te-form 持って threads the action sequence — 'taking [things] and leaving' — implying calculation rather than impulse. Running away from home (家出) is its own social phenomenon in Japan, with associated vocabulary: 家出少女 ('runaway girl'), 家出人 ('runaway').
