Authorities in Pennsylvania arrested a man Thursday in connection with the death of his wife after police allegedly discovered ominous messages on his phone from around the time of her death, per reports.

The Lancaster County District Attorney’s Office had been searching for 48-year-old Matthew Harrison in connection with the death of Jami Harrison on charges of murder, strangulation and sexual assault against , the office said in a statement on Thursday.

Later on Thursday, the Northern Lancaster Regional Police Department issued a statement that the suspect was found at a hotel and had been taken into custody after a brief standoff.

Jami, 49, has been identified by FOX 43, WGAL and ABC 27 as Matthew's wife.

On Monday afternoon, officers from the Northern Lancaster County Regional Police Department responded to a residence in Manheim, Pa., after receiving a 911 call from an 11-year-old child claiming they’d found Jami dead, according to the DA’s office.

The child allegedly alleged to a responding officer that Matthew was “really mean and hurts” Jami, the statement said.

Officers found Jami on her bed with strangulation marks and bruises on different parts of her body, and she displayed “signs of sexual assault,” the statement said.

Her death has been ruled a homicide, per the statement. She died as a result of strangulation.

During the investigation, authorities learned about Matthew's allegedly concerning behavior, the statement claims.

He had allegedly sent Jami “insulting” messages on the days prior to her alleged killing, said the statement. He allegedly told her he would be coming by the house to grab his belongings and sent her 120 messages before she responded, the statement claims.

On the day Jami’s body was found, Matthew allegedly messaged a family member that he had been “having murder on my brain,” the statement said. (According to a probable cause affidavit reviewed by WGAL, Matthew's son was the family member who received this message.)

“If I kill her by now I'm cool son,” Matthew allegedly wrote to his son, according to the probable cause affidavit.

Police also allegedly discovered messages from Matthew to Jami that read, “you’re not getting away with this,” and “how’s that for your marriage,” and “If I’m going down your coming with me,” WGAL reported, citing the affidavit.

Authorities found text messages sent from his phone to a co-worker where he allegedly said he would not be returning and the “demon in me broke free,” per the DA’s office statement.

On Monday, Matthew allegedly checked out of a hotel where he’d been staying, just a few hours before police received the 911 call from Jami’s home reporting Jami's death, per the statement.
