Oh, I had a misunderstanding, or a different interpretation, then as I assumed Maggie trusted the Mexicans because they had been renovating the Edisto beach residence. If that is the case, I would say "my contractors are trusted to lock everything as they leave the job." For me by using the word Mexicans, it signifies cheap labor in exchange for their excellent work habits, skills and trustworthiness.
MM did not have anyone to take care of or to look after anymore with the boys moved out on their own. She and Alex were living apart. Her nest was empty. Her handsome young son may spend the next 30 years in prison in convicted in the drunken boat crash that killed the gorgeous gf of Anthony, Miss Mallory Beach.
On her last day, MM had a Dr. appt., a pedicure and likely purchased new Goosey Gucci sandals, probably the flip flops she wore when walking or pacing, in a perhaps hurried fashion, in a line, under the shed leaving a trail of her shoe prints as she did. I recall she left her car running down at the kennels because she intended to follow Alex to visit his parent. Do I have that right?
The elder Mr and Mrs Murdaugh were transitioning so I wonder if AM expected to inherit a great deal of assets from their estates? AM is maneuvering for a Fed Pen sentence on the Fraud charges, right?
And, there was a repass held for Paul and Maggie where Alex appeared to be sad. Muchelle is a loyal employee to kindly increase her time spent while there was great need.
