LAS VEGAS -- Las Vegas police are investigating a marijuana grow site where a mother and her two sons were arrested over the weekend. Two small children were also in the in the house.

The incident happened at a house on Rancho Palms Drive in northwest Las Vegas. Police say they have responded to the home at least five times in the last 60 days. But they say the valley's marijuana problem is much bigger than one house.

"The problem with marijuana grows has eclipsed that of methamphetamine labs. In 2010, we only had six methamphetamine labs as compared to 118 marijuana grows," said Metro Lt. Laz Chavez.

Since 2007, Metro says the valley has seen more than a 100 percent increase of marijuana grows and plants, a 43 percent increase of people arrested and the investigations have cost the department more than $500,000 since 2007.

LAS VEGAS -- Opportunity Village has suffered another blow. Six months after a fire destroyed the Opportunity Village Thrift Store, vandals have broken into cars and damaged property at their main campus.

When staff arrived at work Wednesday, they saw shards of tinted glass all over the parking lot. Seven vans were broken into and rummaged through. There were even tools stolen out of one of them.

"Can we not catch a break at all? It's very, very frustrating. The staff just can't comprehend why anyone would want to do this to Opportunity Village," said Linda Smith, Associate Executive Director of Opportunity Village.

She says thieves have stolen Santa suits, cables, Christmas lights and props from the Magical Forest over the last month.

LAS VEGAS - A high-end home turned brothel is the talk of Red Scott Circle.

"They had a red light on in the back, pretty much at late hours," said neighbor Partap Khalsa. "It was definitely, ‘We're in business.'"

That business, and the money it generated, may have led to the murder of Young Shil Park. Last month, hikers found the 39-year-old's charred body in Arizona near Hoover Dam.

Metro Police say 30-year-old Min Soon Chang and 19-year-old Keon Kyun Park confessed to Young Shil Park's murder. Police say the men beat her to death, then burned and dumped her body. Keon Kyun Park is not related to the victim.

Police say Park ran an escort service out of the home on Red Scott Circle near South Tenaya Way and West Desert Inn Road. Both men worked for her. Court documents reveal Park owed the men $9,000.
