MARDELA SPRINGS, Md. — Maryland State Police have charged two women with multiple counts of abusing three children in their care.

Authorities say 29-year-old Amanda R. Wright and 25-year-old Besline Joseph were arrested Wednesday morning at their Mardela Springs home following an investigation that began last week. Both are charged with child abuse, assault, reckless endangerment, child neglect, stalking and other offenses.

Investigators say the three victims, ages 8, 9 and 10, resided with Wright and her live-in girlfriend, Joseph.

Officials say an investigation revealed that since late spring or early summer of last year, the children had been beaten several time by both suspects, sustaining bloody noses, bruises and cuts.

Authorities say the women also repeatedly assaulted the children with a stun gun.

It was not immediately clear whether the women have lawyers.
