Dead body of 25-year-old woman was found on a road in Mexico City with traumatic injuries consistent with gettting run over. Police conclusion was that a rival cartel deliberately ran the woman over in what is called vehicular homicide. Not common method of killing someone but certainly not unheard of.
An old case, a woman died of unknown circumstances and found by her sister. Her boyfriend was initially arrested on suspicion of fowl play since he was the last to see her and his semen was found in her vagina. Autopsy shows she died of an overdose and he was released later.
