BREAKING: MOTHER MURDERS FAMILY, SHOOTS MARRIED LOVER THEN KILLS HERSELF

A Greensboro, North Carolina mother went on a shooting rampage on Sunday morning, killing 1 of her children and her niece while shooting her nephew and her son's girlfriend. The 36-year-old Mary Ann Holder reportedly also shot her married lover earlier in the day before later turning the gun on herself.

This shocking murder-suicide happened in Guilford County and left 4 dead and 5 hospitalized in critical condition. According to WFMY TV, Sheriff B. J Barnes called this the worse he has seen in his 30 year career.

Holder apparently had a tumultuous affair with a married man, 40-year-old Randall Lamb, who wanted to end the relationship. On top of that neighbors reported that she took in her niece and nephew after her sister died when she was already overwhelmed with her own.

Things came to this explosive climax over the weekend when Holder reportedly met Lamb for one last goodbye. She shot him at that rendezvous, then went home and carried on her murderous rampage there.

Holder shot her 17-year-old son Robert Dylan Smith in the head, killing him, shot his 15-year-old girlfriend Makayla Leigh Woods, who survived and is in critical condition at the hospital, shot her 8-year-old niece, Hannaleigh Suttles, who died at he hospital on Monday.

Her 14-year-old son Zachary Lee Smith is also in critical condition and so is her 17-year-old nephew Richard brian Suttles. All the children were reportedly shot in the head.

Her married lover's wife was the one who alerted police to the beginning of the rampage. Her husband had called her around 8:52 that Sunday morning to tell her he had been shot by Holder. She called 911 and police found him in his car near the GTCC Aviation center.

Deputies then went to Holder's home on Cocoa Drive in Pleasant Garden, where they found 3 of the children shot and 17-year-old Robert already dead.

Reports say as the deputies approached Holder's vehicle which was parked on Remora Road, they saw a puff of smoke. Law enforcement believe that was when she shot herself. Her 14-year-old son Zachary was found shot in the back seat.

According to WFMY News, Sheriff Barnes said Holder left behind notes stating she took full responsiblity for her actions and asked for forgiveness. The note also implied that the carnage was a result of being wronged by someone--maybe her married lover Lamb. No one may ever know why this mother slaughtered and attempted to wipe out her children and other family members.
