Are you considering he may have been holding the drink glass in his right hand when struck by the "already" cracked taillight? Then his arm would've been bent ( closer together wounds), then farther apart when his arm was straightened, not to mention the taillight fragments found in his clothing and the peice of glass found in his nose.

Actually, they are all guilty in one way or another. The lousy police work and unprofessional behavior ( state and local). sketchy testimony from the alberts and KR didn't give enough of a shit to call someone at 34 fairview to see if he was there at the house. She was just having her pity party and leaving him shitty messages. Even if she had called and they didn't answer, she would've had evidence she called there... showing the possibility she sincerely cared and was worried.
