The $30k is unpaid child support, not court costs. I don't know about SC, but in Texas, minimum child support, depending on the number of kids a guy has, is around $200/month (we take a percentage of net income depending on number of kids). Not only did th guy fail to pay, he also failed to appear in Court to face the legal action for his failure to pay.
I've believed from the beginning, this was murder, taser lost for a time or not, because that harm/threat vanished when the guy turned and ran. But I don't have much sympathy for the guy. Truthfully, his death was the only way his kid(s) was/were going to get support from him as they'll likely now get some settlement.
