Nathan Griffith and his mom Doris Davidson refused to return Kaiser to mom Jenelle Evans after noticing alarming bruise marks on the 4-year-old during a weekend visit. Now, RadarOnline.com can exclusively reveal three frantic 911 calls made by the Teen Mom 2 star.

In the first 911 call obtained from Horry County in South Carolina, Evans called authorities on Sunday, July 1 to report that Griffith and Davidson refused to return Kaiser.

“The grandparent and my ex are trying to keep my son,” Evans, 26, told the 911 operator. “I have primary custody and he has every other weekend. They were supposed to meet me at 5pm at the gas station and now they’re trying to say, ‘Oh since he has a bruise on him we’re going to keep him and not give him back to you.'”

Evans continued that she has proof of their custody agreement and that they did not file an emergency custody order.

“I have primary custody,” she explained. “The father has supervised visits. He’s not even allowed to have him unsupervised. They’re trying to keep him from me!”

In a second call, she asked police to perform a wellness check on her son because she couldn’t get in touch with him during the Child Protective Services and Department of Social Services investigation.

“Over the weekend he got a bruise on his butt,” she explained to the operator. “No one called me about it, but they called and made a police report. DSS is trying to investigate and hold my child at their house.”

She continued, “I’ve been trying to call my child all day, but no one answers the phone. We’re waiting on DSS to finish their investigation and no one will contact me from DSS. They won’t answer to let me talk to my child. I want to send an officer there to see if he’s okay and make sure everything is okay.”

As Radar previously reported, Evans was able to pick her son up on Tuesday, July 3. In the third 911 call, she asked for a police escort during the custody exchange.

“CPS of Columbus County advised me I should have an officer there in case the grandmother gets mad,” Evans explained to the operator. “Over the weekend she tried accusing my husband of child abuse, she had called DSS. They just left my house and told me go get my son. They said take an escort because the grandma might not be happy.”

Griffith, 30, called police on Friday, June 29 and Sunday, July 1 to report child abuse. In the 911 call obtained by Radar, Griffith told authorities, “I received my child and he has marks all over him. We asked him about it and he said [Evans’ husband] David hit him with a stick.”

After an investigation, Davidson was forced to hand Kaiser over to Evans and her husband David Eason. Eason recorded the exchange on Instagram live.

“Say bye to grandma Kaiser… Bye Doris, you’re so lovely,” he said. “She said get off her property. She’s going to have me arrested! F**king ugly b***h. Try to take my kid away from me again!”

The custody battle started in September 2017 when Davidson filed an emergency request for full custody of Kaiser. She accused Evans of testing positive for marijuana at the time of her daughter Ensley’s birth. She also accused Evans and Eason of neglect and abuse.

“There have been several occasions when the proposed Intervenor has seen bruising and markings on the minor child that are unusual and more than normal scrapes that a toddler may have than a two/three year old should have,” Davidson wrote in the documents obtained by Radar. “On April 28, 2017, there was bruising on the minor child’s back. On March 31, 2017 there was a bruise on the minor child’s chest of a fingerprint which appeared as though a finger had been pressed firmly into the minor child’s chest as well as along the minor child’s left arm appearing that he had been jerked by the arm.”
